[Patch 12.9] Yuumi The Magical Cat Guide ᓚᘏᗢ

By pastelzia

Hello! Welcome to my Yuumi Guide for Season 12

My name is Pastel and I'm a Yuumi main. I look forward to teaching you how to play Yuumi! Make sure to comment any suggestions or questions. <3
In this guide I'll be going over everything you need to know about Yuumi The Magical Cat!

- Table Of Contents -

Just for reference, this is my current number of Mastery Points on Yuumi!

If you would like to look me up, my username is pastelzia on NA.




INNATE: Periodically, Yuumi's next basic attack against an Enemy Champion has an uncancelable windup, gains 50 bonus range, turns into a non-projectile, restores 25 − 100 (based on level) (+ 8% maximum Mana ) Mana and grants her a 60 − 400 (based on level) (+ 30% AP) shield that lasts until it is broken. While using You and Me! on an allied Champion, the shield transfers to her allied champion who becomes her current friend.


Try to detach using You and Me! every now and then when you know it is safe to use Bop 'n' Block (when enemies use important abilities) to restore Mana and grant a shield to your current friend.


ACTIVE: Yuumi fires an errant missile in the target direction that deals magic damage to the first Enemy it hits. If the missile is in flight for 1 second, it deals increased % Current Health magic damage, and if the target is a Champion, slows by 20% for 1 second. The percent current health bonus damage is capped at 50 − 300 (based on level) against minions and monsters. While attached, Yuumi instead channels for up to 2 seconds, directing the missile with her cursor, after which it fizzles.


You can use You and Me! to extend the range of this ability, as you can continue using it while using You and Me! on other friends.


ACTIVE: Yuumi channels for 0.25 seconds, then dashes to the target allied champion upon completion and Yuumi attaches to them upon arrival. While attached, Yuumi is untargetable (except from turrets and in-flight projectiles targeting her) and casts her spells from the current friend's position. The cooldown starts upon completing the channel. You and Me! can be recast after 0.5 seconds of attachment. Yuumi will be knocked down by any immobilizing crowd control during the dash. and the cooldown of this ability will be reset for 5 seconds and Yuumi cannot use You and Me! during this time.

RECAST: Yuumi can switch her current friend, refreshing the recast. She will detach automatically if her current friend dies or under certain circumstances Realm of Death, etc. If recast without a valid target or on the ground, Yuumi will detach from her current friend and dash 250 units in the target direction, putting the ability on cooldown. Regardless of cooldown, You and Me! can't be cast again for 0.5 seconds after the attachment if recasting with a valid target, or for 0.2 seconds if recasting without a valid target.

PASSIVE: The current friend gains either a flat and percentage amount of their bonus attack damage or a flat and percentage amount of their ability power, based on whichever was initially higher. The percentage bonus of You and Me! also benefits from its flat bonus. Yuumi then gains flat adaptive force. Additionally, Yuumi starts with a point in You and Me! and Prowling Projectile instead has 6 ranks of which you can put points into the ability whenever Yuumi gains a champion level.

Many Champion abilities can be affect Yuumi during You and Me! under certain circumstances such as when Yuumi has been detached from You and Me! recently, and a Champion ability has been used on her during the You and Me! animation, or when You and Me! was not active on an allied champion at the time of the ability cast.
Abilities that can be used at this time include: in-flight projectiles & targeted ability/spell casts, tethers, delayed abilities, burn damage, other.


This can be cancelled by most hard crowd control abilities, so only use this if you are sure you are not at risk of having this ability cancelled. Meaning attaching from ally to ally aswell. You will die most of the time if this gets cancelled.
Aswell as you can use You and Me! to give allies Summon Aery's shield quickly. Also please ping assistance and fall back ping on your ally you want to attach a few times until they let you. :( TAKE THE CAT!


ACTIVE: Yuumi heals herself for 70 / 105 / 140 / 175 / 210 (+ 40% AP) and gains 15% (+ 10% per 100 AP) bonus movement speed and bonus attack speed of 25 / 30 / 35 / 40 / 45% for 3 seconds. While attached, Yuumi's current friend is affected by Zoomies instead.


This can be very useful to give Summon Aery shield in scary situations and the attack speed and movement speed aswell for fighting enemies and chasing enemies also for running away too.

FINAL CHAPTER - R (Ultimate)

ACTIVE: Yuumi and Book channel for up to 3.5 seconds, launching 7 waves dealing 60 / 80 / 100 (+ 20% AP) in the target direction over the duration, each dealing magic damage to all enemies within their path. Enemy Champions hit take only 50% damage from subsequent waves, and when they are struck by three waves, they become rooted for 1.75 seconds. This may only occur once per target.


Use this for engaging and running away. It does a ton of damage when you get a lot of ability power aswell so make sure to use it every big teamfight you can. Try to aim it in the direction your enemies are probably going to walk but make sure it is on the Enemy Champion(s) too.

Skill Sequence


70 / 100 / 130 / 160 / 190 (+ 35% AP) Heal
25 / 30 / 35 / 40 / 45% Attack Speed

Prowling Projectile

50 / 80 / 110 / 140 / 170 / 200 (+ 30% Ability Power) Damage
You and Me!

12 / 14 / 16 / 18 / 20 Adaptive Force + 20% of Ally affected with You and Me! Adaptive Force
Final Chapter

60 / 80 / 100 (+ 20% AP) Damage Per Wave
> > >
This is the leveling order most Yuumi players go, its really good it gives you healing and damage mixed.

Putting 3 points into Prowling Projectile then maxing Zoomies is also viable because it gives you a little bit more damage in the early laning phase. But you still prioritize Zoomies first.


70 / 100 / 130 / 160 / 190 (+ 35% AP) Heal
25 / 30 / 35 / 40 / 45% Attack Speed

You and Me!

12 / 14 / 16 / 18 / 20 Adaptive Force + 20% of Ally affected with You and Me! Adaptive Force
Prowling Projectile

50 / 80 / 110 / 140 / 170 / 200 (+ 30% Ability Power) Damage
Final Chapter

60 / 80 / 100 (+ 20% AP) Damage Per Wave
> > >
I like this leveling order because it gives you the most buffing power. But it is not that great if your ally is really dumb and bad so dont go this every game unless you are in a duo with someone you trust!

Prowling Projectile is not as useful to max second as You and Me! SOMETIMES in certain situations since your Prowling Projectile Ability Power ratio is not the best and it's only one ability compared to your ally's entire kit getting buffed with adaptive force.
Do this if you have a hypercarry like Kog'Maw, Vayne, Jinx, or anyone who is super fed on your team that you can 2v5 with. Otherwise, go E>Q>W>R.

Pros and Cons
+ Great teamfighter.
+ Amazing mid-late game scaling.
+ Good healing + shielding.
+ Easy to pick up and start playing.
+ Fun to play.
+ She's a cat and is really cute + has good skins!
- Squishy
- Bad lane pressure early game pre level 6.
- Ally dependant.
- Roams are not very good without a good jungler.
- Is banned consistently as of recently. :(
- Bad against high crowd control team compositions.
Summoner Spells

HEAL: Heal Scales with Heal and Shield power meaning this summoner spell is best taken with Heal and Shield Power items such as Moonstone Renewer, Redemption, Staff of Flowing Water, Ardent Censer, and Mikael's Blessing.
When Yuumi uses Heal, Yuumi Heals herself and the allied champion nearest to Yuumi's cursor (prioritizes the most wounded allied champion if no allied champions are near the cursor) for 90 − 345 (based on level), while also granting both of you 30% bonus movement speed for 1 second.
Champions affected by Heal within 35 seconds cause subsequent Heal casts on them to restore 50% less health.
IGNITE: Ignite is an aggressive summoner spell for Yuumi and is paired well with Exhaust for maximum kill threat.
When Yuumi uses Ignite, she sets the target enemy champion on fire for 5 seconds, revealing them and dealing 70 − 410 (based on level) True Damage over the duration, with the first tick of damage occurring on-cast and subsequent ticks occurring each 1.25 seconds. The target is also inflicted with 60% Grievous Wounds for the same duration.
EXHAUST: Exhaust is a defensive and offensive summoner spell for Yuumi and can be paired with any of the summoner spells above.
When Yuumi uses Exhaust, she weakens the target enemy champion, slow ing them by 30% and reducing their damage dealt by 40% for 3 seconds.

Why not bring Flash?

Yuumi does not need Flash believe it or not. She is completely safe as long as she is with her ally or allies, thanks to You and Me! Yuumi has good mobility, especially with Zoomies movement speed . Yuumi only loses her mobility whenever she is alone, but she should never be alone anyway because of how her kit is centered around You and Me! and relies on it heavily because You and Me! gives all of Yuumi's abilities bonus properties. Also Yuumi cannot use Flash while using You and Me! so it makes it signifigantly worse. Thats why Flash is not good or neccessary on Yuumi.


Sorcery is the best primary rune tree for Yuumi it suits her playstyle and build paths very well.


Summon Aery is the best keystone on Yuumi and it suits her kit perfectly. Summon Aery can be utilized in 2 different ways, damage and shielding, both of which Yuumi can utilize. Using Yuumi's Prowling Projectile, Final Chapter and her Basic Attacks she can deal damage with the Summon Aery Rune. Using Yuumi's You and Me! and Zoomies Yuumi can give a Shield to her allies and friends. There is basically no other keystone that gives Yuumi as many benefits as Summon Aery and gives the Sorcery tree which is the best primary Rune Tree for Yuumi.


Manaflow Band is great for Yuumi's poking abilities in lane by giving her more mana to use for her Prowling Projectile and Zoomies. Manaflow Band allows Yuumi to gain Mana up to a cap of 250 by using her damaging spells and abilities including Prowling Projectile and Final Chapter (but usually only Prowling Projectile but you will most likely have Manaflow Band completely stacked by the time you reach Level 6 to gain Final Chapter. After Manaflow Band is completely stacked to 250 Mana , every 5 seconds you will regenerate 1% of Yuumi's missing Mana .


Transcendence Is one of the best runes in the game for Yuumi as it synergises well with her playstyle of spamming spells and abilities. Transcendence gives Ability Haste and Cooldown Reduction per level.
At level 5 Yuumi gains 5 Ability Haste.
At level 8 Yuumi gains another 5 Ability Haste.
At level 11 Yuumi's remaining spell cooldowns are reduced by 20% whenever Yuumi gains a Champion Takedown. (Kill or Assist) This rune is great on Yuumi because her ability cooldowns are pretty high without any Ability Haste or Cooldown Reduction and they are all essential for her to use consistently.


Gathering Storm is great on most scaling champions, Yuumi included. Yuumi utalizes Gathering Storm's additional Ability Power that is granted over the course of the game very well because all of Yuumi's abilities ( Bop 'n' Block, Prowling Projectile, You and Me!, Zoomies and Final Chapter) scale with Ability Power. In general, Yuumi does not have as much of a threatening lane as some other champions like Lux, Vel'Koz, or Zyra so Gathering Storm is going to be better in most games unless you are facing a champion that is easily abusable and easy to poke and use Prowling Projectile on. In that case, you would go Scorch.


Precision is one of the options you can go for secondary rune tree's as Yuumi.


Presence of Mind is a great rune for late game teamfighting as Yuumi because it allows you to have amazing Mana sustain to be able to keep casting spells and abilities throughout the fight because scoring a Takedown against an Enemy Champion restores 15% of your maximum Mana . Also, damaging an enemy champion increases Yuumi's Mana regeneration by 1.2 to 8.8(based on level) Mana per second for 4 seconds. In general Presence of Mind is a pretty good rune for Yuumi for Mana regeneration and sustain, and is especially good before Yuumi gets her Mana regeneration items. Mana regeneration is especially good on Yuumi because of her Zoomies Mana cost scaling with 15% of Yuumi's maximum Mana , so building Mana is not as gold efficient on Yuumi as another Champion like Sona.


Cut Down is a decent rune on Yuumi in the early game because most Champions will have more maximum health than Yuumi. After the early game, the rune becomes weaker on Yuumi because she builds health items such as Moonstone Renewer, Shurelya's Battlesong, Everfrost, Redemption, Knight's Vow, and Shadowflame which all give bonus health making this rune not as effective for Yuumi. However, this rune is great against tank champions such as Ornn, Nautilus, Alistar, Leona, Cho'Gath, etc. So make sure to bring this rune if they have 2 or more tanks but feel free to go it if you are facing a tank support.

If the Enemy Team has a lot of Crowd Control threats, I strongly recommend taking Legend: Tenacity instead of Cut Down as it gives a lot of help for Yuumi whenever her You and Me! animation gets cancelled by Crowd Control and helps prevent as many deaths.

Resolve is one of the options you can go for secondary rune tree's as Yuumi.


Font of Life is a good rune for Yuumi because it allows her to heal her allies even more. Whenever Yuumi applies a Slow or immobilizing effect to an Enemy Champion, she marks them for 4 seconds. Allied champions (excluding Yuumi) who basic attack marked enemies heal for 5 (+ 1% of your maximum health) over 1.75 seconds. This allows Yuumi to give even more utility and sustain to her allies in combat.

If you are facing an Enemy Champion that is more abusable and easier to poke down in lane, you can instead take Shield Bash which applies on your Bop 'n' Block basic attack allowing you to do bonus poke damage to enemies whenever you initially hit the Bop 'n' Block basic attack, and while you have the Bop 'n' Block shield on Yuumi.


Revitalize is a great rune for Yuumi as it increases all of her healing and shielding. Revitalize grants Yuumi 5% Heal and Shield Power. Outgoing healing and outgoing shielding casted by Yuumi or used on Yuumi are increased by 10% on targets below 40% of their maximum health. Also, Incoming healing, incoming shielding, self healing and self shielding are increased by 10% while you are below 40% of your maximum health. In general this is one of the best runes ever for Yuumi as it grants her tons more healing for herself and her allies!

Inspiration is one of the options you can go for secondary rune tree's as Yuumi.


Biscuit Delivery is a early laning rune that helps a lot with Mana sustain and health sustain. Yuumi Will receive a Total Biscuit of Everlasting Will at 2:00, 4:00 and 6:00. If Yuumi's inventory is full while receiving a biscuit, the biscuit(s) will appear as soon as a slot in Yuumi's inventory is available. Meaning that this rune is especially effective in early laning phase throughout 2:00 to 6:00 minutes into the game. Consuming a Total Biscuit of Everlasting Will instantly grants Yuumi 50 Mana and permanently increase your maximum Mana by 50, in addition to its effects. You will also gain the increased mana if you sell the Total Biscuit of Everlasting Will. Each Total Biscuit of Everlasting Will grants 5 Gold when sold to the shop keeper.

If you are not in a lane that you think you will be trading with the Enemy laners a lot, then it is better to go Future's Market instead. Future's Market allows Yuumi to enter debt to buy items, up to 145 (+ 5 Gold per minute), which is displayed as negative gold in Yuumi's Gold inventory.


Cosmic Insight grants Yuumi 18 summoner spell haste and 10 item haste. These are amazing stats for Yuumi because she uses a lot of items that have cooldowns such as Moonstone Renewer, Shurelya's Battlesong, Mikael's Blessing, Everfrost, Redemption, etc. Yuumi also does not bring Flash meaning that Yuumi's Summoner Spells will be a relatively low cooldown already, in comparison to other Champion's Flash cooldown. 18 summoner spell haste reduces these spells cooldowns quite a bit more making her summoner spells very low cooldown.

Domination is one of the options you can go for secondary rune tree's as Yuumi.


Ghost Poro Allows Yuumi to have a lot of vision control. This rune is good for placing multiple wards. If 3 of your wards expire, you will then have 3 Ghost Poro's in that area where those wards were placed, so you can place 3 new wards and have technically 6 wards. This is just an example and it provides lots of vision.

Yuumi can also take Zombie Ward. This rune is great in higher elo (Platinum+) because players will place more wards.
Scoring a Takedown against an Enemy ward within 10 seconds of damaging it summons an allied Zombie Ward in its place.
Zombie Wards grant sight in a radius of 900, are untargetable to your allies, are visible to the enemy team, have 1 health, last for 120 seconds and don't count towards Yuumi's ward limit.

Both of these runes Ghost Poro and Zombie Ward have a shared passive.
Yuumi gains 1.2 bonus Attack Damage or 2 Ability Power (Adaptive) for every Zombie Ward/ Ghost Poro spawned, up to 10, for a maximum of 12 bonus Attack Damage or 20 Ability Power (Adaptive). After spawning 10 Zombie Wards/ Ghost Poros, gain an additional 6 bonus Attack Damage or 10 Ability Power (Adaptive).


Ingenious Hunter is similar to Cosmic Insight but grants more Item Haste than Cosmic Insight, so Ingenious Hunter is better if you are against a lane opponent you have to play more passively towards as Ingenious Hunter is a more passive rune than Biscuit Delivery. But it all comes down to preference if you want Mana from Inspiration > Biscuit Delivery or Vision from Domination > Ghost Poro/ Zombie Ward.

Whenever Yuumi has Ingenious Hunter she gains the ability to:
Earn a Bounty Hunter stack whenever scoring a Takedown against an Enemy Champion, up to one per unique champion.
Yuumi gains 20 (+ 6 per Bounty Hunter stack) item haste, up to 50 at 5 stacks.

This is a giant ammount of Item Haste and this rune is incredibly strong because of it. The only downside to this rune that makes a big difference between Ingenious Hunter and Cosmic Insight is that Ingenious Hunter takes longer to stack, whereas Cosmic Insight grants Yuumi Item Haste immediately.

Stat Shards

I recommend going Shield or Circle instead of Heart if you choose to go Cut Down.

These are all the best and most viable runes for Yuumi at this current time! :)



This item is super amazing, it gives Yuumi everything she wants. It is so good all of the stats are useful on Yuumi and perfect for her kit. I strongly recommend this item! :D

+40 Ability Power
+20 Ability Haste
+200 Health
+100% Base Mana Regeneration

UNIQUE – STARLIT GRACE: When affecting champions with attacks or abilities in combat, heal the nearby allied champion (excluding yourself) with the most missing health for 70 (2 second cooldown). Each second spent in combat with champions grants 6% heal and shield power, stacking up to 5 times for maximum of 30%.

MYTHIC PASSIVE: Empowers each of your other Legendary items with 10 heal for this item's passive effect, Starlit Grace.


This item is pretty good. The stats are great and the mythic passive gives bonus Abiltiy Haste per legendary item which Yuumi loves! (none of the other mythic options for Yuumi have this) This item is good for engaging and escaping and gives your team lots of movement speed .

+40 Ability Power
+20 Ability Haste
+200 Health
+100% Base Mana Regeneration

UNIQUE – INSPIRE: Grants you and all allies within 1000 units of you 30% bonus movement speed for 4 seconds (75 second cooldown).

UNIQUE – MOTIVATE: Healing, shielding, or buffing allied champions (excluding yourself) grants you and them 25% bonus movement speed for 1.5 seconds (4 (per champion) second cooldown).

MYTHIC PASSIVE: Empowers each of your other Legendary items with 5 ability haste.


This item is good for extra damage but only if you are likely to proc the passive.
Only go this if the enemy team will usually be far away from you, so you can get the empowered Prowling Projectile and the root on Yuumi's Final Chapter.

+40 Ability Power
+20 Ability Haste
+200 Health
+100% Base Mana Regeneration

UNIQUE – COORDINATED FIRE: Abilities that slow or immobilize Enemy Champions deal 45 − 75 (based on level) bonus magic damage and mark them for 4 seconds. Allied champions that damage marked enemies consume the mark to deal 90 − 150 (based on ally's level) bonus magic damage and grant you and the triggering ally 20% bonus movement speed for 2 seconds (6 (per champion, starts upon mark application) second cooldown).

MYTHIC PASSIVE: Empowers each of your other Legendary items with 15 Ability Power.


Everfrost is pretty good for lots of Ability Power and if your team needs more engage, since it gives them a Crowd Control to follow up on. It recently got super buffed in Season 12. It is now a lot cheaper! So the item is more accessable for supports like Yuumi.

+70 Ability Power
+20 Ability Haste
+250 Health
+600 Mana

UNIQUE – GLACIATE: Unleash a fan of icy shards in a cone in the target direction, dealing 100 (+ 30% AP) magic damage to all enemies hit and slow ing them by 65% for 1.5 seconds. Enemies struck in the center of the cone are rooted for the same duration instead (30 second cooldown).

MYTHIC PASSIVE: Empowers each of your other Legendary items with 10 ability power.LEGENDARY ITEMS


Staff of Flowing Water is the best Legendary Item for Yuumi by far. Allowing for Yuumi to use her spells and abilities more often by giving her Ability Haste and giving her more Ability Power, along with the Allied Champion Yuumi is using You and Me! on. This item gives Ability Power, so it is better to get second item after your Mythic Item instead of Ardent Censer if you have a lot of Ability Power Allied Champions on your team such as Ahri, Malzahar, Ziggs, Xerath, etc.

+50 Ability Power
+100% Base Mana Regeneration
+10% Heal and Shield Power

UNIQUE – RAPIDS: Healing or shielding Allied Champions (excluding yourself) grants you and them 25 − 45 (based on target's level) Ability Power and 20 Ability Haste for 4 seconds.


Ardent Censer gives Yuumi the ability to buff her allies who rely more on on-hit abilities and Attack Speed. Ardent Censer gives Yuumi along with the Allied Champion Yuumi is using You and Me! on, on-hit damage and Attack Speed. Ardent Censer is better to get second item after your Mythic Item instead of Staff of Flowing Water if you have a lot of Attack Damage or Attack Speed based Allied Champions on your team such as most Ad Carry champions like Jinx, Twitch, Vayne, etc. Along with some other champions who also use Attack Damage or on-hit and Attack Speed such as Jax, Irelia, Wukong, Master Yi, Gwen, Kayle etc.

+60 Ability Power
+100% Base Mana Regeneration
+10% Heal and Shield Power

UNIQUE – SANCTIFY: Healing or shielding allied champions (excluding yourself) enhances you and them with 10% − 30% (based on target's level) bonus attack speed and 5 − 20 (based on target's level) bonus magic damage on-hit on basic attacks for 6 seconds.


Mikael's Blessing allows Yuumi to have a Cleanse basically as an item. Mikael's Blessing is a little worse than Cleanse though because Mikael's Blessing Active can only be used on certain Crowd Control. In general this item is pretty good though since it Heals your ally aswell, not only Cleanseing them.

+15 Ability Haste
+100% Base Mana Regeneration
+50 Magic Resistance
+20% Heal and Shield Power

UNIQUE – PURIFY: Remove all crowd control debuffs (except Airborne, Blind, Disarm, Ground, Nearsight, and Suppression) from yourself or an Allied Champion and Heal the target for 100 − 200 (based on target's level) (120 second cooldown).


Redemption is a great item for Yuumi for teamfights since it gives Area Of Effect healing to your team in a circle in an area, and also does True Damage to enemies in the circle. It is still situational since it has a short period where it has to charge up the heal, so make sure to use it early before your allies die.
This item's active heal also scales with Heal and Shield Power, meaning it can be increased by it.

+15 Ability Haste
+100% Base Mana Regeneration
+50 Magic Resistance
+20% Heal and Shield Power

UNIQUE – PURIFY: Remove all crowd control debuffs (except Airborne, Blind, Disarm, Ground, Nearsight, and Suppression) from yourself or an allied champion and heal the target for 100 − 200 (based on target's level) (120 second cooldown).


Mejai's Soulstealer builds from Dark Seal which is a very cheap item and is a must buy every game on first back if you have 350 Gold for Dark Seal.
Mejai's Soulstealer is an amazing on Yuumi and is very easy to stack if you can ensure that you don't die and lose the stacks which is pretty easy to do on Yuumi because she is Untargetable in You and Me! and Heals Allies that she is using You and Me! on with Zoomies meaning that Yuumi probably won't die if she can keep her Ally alive in those situations.
(just be smart and don't use You and Me! on an ally who will most likely die and has been doing so all game.)

+20 Ability Power
+100 Health

UNIQUE – GLORY: Gain 4 stacks for each champion kill and 2 stacks for each assist, up to a maximum of 25 stacks. Lose 10 stacks on death. Stacks are Dark Seal.

UNIQUE – DREAD: Gain 5 ability power for each stack of Glory and 10% bonus movement speed if you have at least 10 stacks.


This item is great to buy if you have a lot of Gold. You can build this in any build on Yuumi and it will be great, since she has abilities that scale with Ability Power since this item gives a lot of Ability Power.

+120 Ability Power

UNIQUE – MAGICAL OPUS: Increase your Ability Power by 35% of your current Ability Power.


This is one of the new Season 12 items. It gives magic penetration depending on the enemy's current health and also if they were recently affected by a shield. This item is great against shield supports or champions who have shields. Only build Shadowflame if the Enemy Team has a lot of champions who have Shield items or Shields in their kits, items, Summoner Spells, etc.(some examples of shield items include, Immortal Shieldbow, Hexdrinker, Maw of Malmortius, Bloodthirster, Eclipse, Fimbulwinter, Gargoyle Stoneplate, Sterak's Gage, Locket of the Iron Solari, etc.) (Some examples of shield Runes and Summoner Spells include, Barrier, Overheal, etc.) (Some examples of shield Abilities include, Haymaker, Blast Shield, Way of the Wanderer, Spirit Cleave, Indestructible, Titan's Wrath etc.) Enemy Champions with low Max Health or if your team will be likely to get them low Health.

+100 Ability Power
+200 Health

UNIQUE – CINDERBLOOM: Dealing magic damage to champions ignores 10 − 20 (based on target's current health) of their magic resistance, increased to maximum value if the they were affected by a shield within the last 5 seconds.


Void Staff is a Magic Penetration item. It gives a lot of Magic Penetration and is good if your Enemies are building a lot of Magic Resistance. It gives a decent amount of Ability Power which and helps with Yuumi's Ability Power ratio's on her Abilities including Bop 'n' Block, Prowling Projectile, Zoomies, and Final Chapter, giving Yuumi increased damage, Healing, and Shielding.
This item is not as effective if the Enemy Team does not have a lot of magic resistance.

+65 Ability Power
+45% Magic Penetration


Horizon Focus has been updated in Season 12. It gives you bonus damage on enemies you hit for 6 seconds if you affect them with a slow or immobilizing Crowd Control or you use an Ability at 700 or more range. It works on Yuumi's Prowling Projectile and her Final Chapter. This item also gives Ability Haste and Health which is much better because you only lose a 30 Ability Power from the changes which is worth around 500 Gold, in exchange for 15 Ability Haste and Health which combined are worth more gold than 30 Ability Power, making Horizon Focus a more Gold efficient item especially for Yuumi.

+85 Ability Power
+15 Ability Haste
+150 Health

UNIQUE – HYPERSHOT: Dealing ability damage to a champion with an ability that is neither unit-targeted nor auto-targeted at more than 700 units away or slow ing,
immobilizing or polymorphing reveals them and increases your damage dealt to them by 10% for 6 seconds. (Damage increase applies on Yuumi's % Current Health damage on Prowling Projectile.


Chemtech Putrifier builds from Oblivion Orb which is a cheap item that is easily accessible for Yuumi for only 800 Gold.
Chemtech Putrifier is amazing since it gives 2 Grievous Wounds items for one! (Grievous Wounds reduced healing) Chemtech Putrifier also has amazing stats for Yuumi giving her Ability Power, Ability Haste, and Mana Regeneration.

This passive can be used on Yuumi's Summon Aery, Moonstone Renewer, Mikael's Blessing, Redemption and Zoomies.


Knight's Vow is good if you have 1 or 2 allies that you NEED to stay alive. It reduces the incoming damage from the ally that you have this item bound to, and heals you for a percentage of your allies damage that you have Knight's Vow bound to. Its really useful on Yuumi since she's untargetable when using You and Me! on an ally and her health doesn't matter as much as other champions because of You and Me!

+10 Ability Haste

+150% Base Health Regeneration

UNIQUE – PLEDGE: Designate an allied champion as Worthy, forming tether between you and them. Champions can only be designated as Worthy by one Knight's Vow at a time (60 second cooldown).

UNIQUE – SACRIFICE: While your Worthy ally is nearby and you are above 30% of your maximum health, redirect 10% of the post-mitigation physical and magic damage they take to you as true damage and heal for 8% of the damage dealt by your Worthy ally to champions.

Please do not build Zhonya's Hourglass unless you are constantly getting your You and Me! animation cancelled by Crowd Control. This item is useful if you are constantly getting crowd controlled as it buys you time for your team to arrive or for your enemies to die. Otherwise, dont build this item as a core item in your builds in most games. Yuumi can use UNIQUE – STASIS when she has arrived to the target ally with You and Me! in order to negate damage to Yuumi with an ability that has already been casted on Yuumi. Some examples of this are Ignite, Malefic Visions, Liandry's Anguish, Demonic Embrace, Blaze, In-flight projectiles such as Disintegrate, Siphon Power, Rune Prison, Tether abilities such as, Test of Spirit, Focused Resolve/ Renewal, Beartrap on a Rope, Ethereal Chains/ Mimic Ethereal Chains, Soul Shackles, and Stretching Strikes. Along with some other abilities that can be used on Yuumi in You and Me! under certain circumstances.

Oracle Lens is good if you have an ally that will be pathing in places you want to use this trinket on because you will be attached to them with You and Me! (preferably a duo partner so you have more synergy and communication.)
It blinds enemy wards in its path and allows you to reveal enemy wards too so you can remove them and deny vision.

Farsight Alteration is great in geenral and has a huge range and is good in most circumstances. Great for checking objectives without having to facecheck areas with no vision. You will be missing out on Stealth Wards and Oracle Lens if you get this trinket though as it has a longer cooldown than both of them, but most players prefer to go Oracle Lens or Stealth Ward anyway so it tends to not matter. Go Farsight Alteration if you don't know what trinket ward to go.

Stealth Ward is pretty good in general, its what you buy when you first start the game always 100% of the time along with your support item Spellthief's Edge.
It has a low cooldown and can hold up to 2 charges and have 3 of them on the map at a time. (this is the same as your support item wards, so if you have 3 Stealth Wards on the map currently, if you place a Frostfang or Shard of True Ice ward, it will replace the Stealth Ward that is closest to expiring with your new ward you just placed down on the map.) Most of the time you will replace Stealth Ward for Oracle Lens or Farsight Alteration once you complete your support item Spellthief's Edge/ Frostfang/ Shard of True Ice.


Watchful Wardstone is a good item but it does take up an inventory slot. It can store up to 3 Control Wards and increases your ward cap on wards you can have placed at a time to 4 Stealth Wards or Frostfang/ Shard of True Ice wards and 2 Control Wards Instead of 3 Stealth Wards or Frostfang/ Shard of True Ice ward and 1 Control Ward.

Early Game

What items do I start on Yuumi, and what items should I get on my first-second back?

When you start the game, every game on Yuumi you want to start Spellthief's Edge and either a Control Ward, or 2 Health Potions.

Start a Control Ward with your Spellthief's Edge if you think that you are in a lane that you will not be able to detach from You and Me! in because the enemy botlane has crowd control threats such as Nautilus, Pantheon, Leona, etc.

Start 2 Health Potions with your Spellthief's Edge in lanes that you will be experiencing a lot of poke back whenever you try to proc Bop 'n' Block on enemy champions with high poke threat and damage early that you can still proc Bop 'n' Block without getting Crowd Controlled in such as Karma, Vel'Koz, Brand, etc.

On your first back as Yuumi,
you should always try to buy a component to one of your Mythic Items such as Moonstone Renewer, Shurelya's Battlesong, Imperial Mandate, or Everfrost. If you can't afford one of these components, you can choose between a few cheaper components to items that you will build that are also very good. Such as Dark Seal, Faerie Charm, Ruby Crystal, Amplifying Tome etc.

What should I do during the early laning phase as Yuumi?

Yuumi is pretty weak before level 6 in the early laning phase, so you won't have any kill-threat or much lane pressure before then. You can still try to bully your opponents out of lane though, but it all depends on the matchup. Some matchups you cant do anything against unless your opponents mess up. Most of the time you want to be attached and utalizing your You and Me! Adaptive Force to your advantage and focus on wave control to try and make it easier for your Ad Carry to farm.

For example into an easier matchup, you should be actively looking for windows to detach from You and Me! to bully your opponents with basic attacks. Poking enemies with basic attacks into a Karma, Vel'Koz, Brand, etc. (basically any opponent that does not have an easily accessable hard crowd control ability or if they do have one, it is easy to dodge) Is pretty easy, as you have Bop 'n' Block's shield to help sustain you so you can take a little bit of damage. Pairing this poking playstyle with Shield Bash works well because you are able to consistently proc it with Bop 'n' Block basic attacks + shield.
A bad matchup for example, into a Leona or Nautilus, it is too risky to detach to bully them with basic attacks. Using your You and Me! Yuumi provides Adaptive Force to her ally, so you want to make sure to be on your Ad Carry whenever there is no opportunities to poke.
What you can do however, is whenever the enemy uses their big crowd control ability, you can detach and start bullying them as if they dont have the ability at all until it is back up. If you need more help on matchups and how Champions work, you can look at the League of Legends Wiki and search for a Champion to see their abilities information, such as cooldowns. (Make sure that when you search you see the /Lol text next to their name and it will be their abilities page. You can do this for any Champion, not just Yuumi. In general, Yuumi can bully enemies out of lane with Prowling Projectile no matter what the matchup is. Use Prowling Projectile every time its up for maximum poke and Spellthief's Edge procs. Enough poking with Prowling Projectile and Basic Attacks, and they should be low enough to kill with your Ad Carry, even before level 6. Especially if you have an aggressive Ad Carry such as Draven, Lucian, Vayne, Tristana, Samira, etc. They do a lot of damage early game and combined with Yuumi it is even more survivability and damage along with attack speed and movement speed from Zoomies.

To prevent running out of Mana , continue using Bop 'n' Block for mana restoration. You can also pick up a Faerie Charm first back to help with this as well if you are having a lot of problems.

Yuumi is great at chasing enemies down with Zoomies movement speed and Prowling Projectile's slow . Building Shurelya's Battlesong makes it even easier to chase enemies down to their death. Especially with an Ad Carry like Draven, Miss Fortune, Ashe, etc. You can usually pick up early kills with these Ad Carries with their amazing chase potential with Blood Rush, Frost Shot, and Make it Rain. Just a little tip, you can try to sit in brush with your Ad Carry and look for sneaky Final Chapters too. If your opponent does manage to fall for it, you should be able to snag a free kill.

Can Yuumi roam?

Yuumi can roam sometimes, but for the most part no. Yuumi cannot roam by herself, however, Yuumi is great at roaming with her jungler.
Some good junglers for Yuumi are Kayn, Lee Sin, Kha'Zix, Rengar, Nocturne, etc. (Basically any bruiser or assassin jungler is going to be good with Yuumi.) Whenever your Jungler ganks, attach to them with You and Me! and look for a gank Mid lane. Ping Assistance and then Ping your jungler and Ping your Final Chapter. It should be a free kill as long as your jungler can follow up on Final Chapter. You can also path towards Mid or Top (usually Mid because it's closer to Bot lane.) after you recall and do the same pings to your Top/Mid as well as Jungle and see if there is an opportunity for a pick. You can look for Final Chapter's over walls for sneaky roots. If you have a Mid laner with Crowd Control, you can also follow up on their Crowd Control with Final Chapter + your jungler's abilities such as Curse of the Sad Mummy or Cease and Desist, etc.
Basically Yuumi can roam after reaching level 6 and with ally help.


Overall, Yuumi's pre-level 6 is not very good, but she can still tend to bully and punish her enemies well during the laning phase and scales very well, taking over the lane after reaching level 6.

Mid Game & Late Game

How do I transition to mid/late game as Yuumi?

The first thing you need to do before you can start impacting the map and doing things in the mid & late game as Yuumi, is to find out who your win condition is. With Yuumi, your allies are everything, your win condition can be something else, but it relies around Yuumi being able to buff and help someone on her team carry and succeed. The easiest way to know, is by seeing who on your team is the best Yuumi fit champion. Champions that are good with Yuumi usually are Assassins and/or Bruisers. These champions are great for Yuumi, because they are great in the meta right now. All of the items for these champions are great such as Axiom Arc, Serylda's Grudge, Goredrinker, Lord Dominik's Regards, The Collector, Divine Sunderer, etc. These champions are usually melee and allow Yuumi easy access to her passive Bop 'n' Block because they have to dive in to get to their and enemies, as well as allow her easy access to getting big game changing Final Chapter's. These champions however, are usually not very useful without a lead, so try to pick out ones with a lead of Minion Kills, Tower Platings, Towers, Kills, Assists, etc. It also goes around if the enemy team comp makes it easier to shut down this champion, if so maybe it is not as good to be on them because they might die and leave Yuumi vulnerable. For example, who do you think will be your carry in this situation? Have a look at the scoreboard.

Ally Team

| Irelia - 2/7/2 - 45 CS
| Hecarim - 7/3/6 - 200 CS
| Malzahar - 3/3/6 - 160 CS
| Jinx - 6/3/4 - 150 CS
| Yuumi - 0/1/9 - 2 CS

Enemy Team

| Tryndamere - 7/4/2 - 190 CS
| Kindred - 3/4/7 - 160 CS
| Yasuo - 3/3/2 - 150 CS
| Xayah - 2/5/0 - 100 CS
| Sona - 0/3/1 - 12 CS

In this scenario, Hecarim is ahead and though hes not super ahead of Kindred, he has a Yuumi which basically secures that he does not die if he plays correctly. Also, their team has 4 Attack Damage Champions, making it very easy for Hecarim to snowball and be very hard to kill if he builds for example a Death's Dance and Plated Steelcaps. This is just an example, and this will not be the case every game ofcourse.

Once you've found what champion is your primary win condition, Yuumi needs to be useful for this champion. So try to build items for this champion's kit in particular. For example, if you have a Hecarim jungle who is your win condition, (as shown above) Ardent Censer is a great item for Hecarim and also synergizes well with the rest of Yuumi's team with Irelia and Jinx. Both of which are Attack Damage champions, meaning that they can utilize Attack Speed from Ardent Censer to get more attacks to do more damage. For example if you had a Singed, Ahri, and a Lillia it would be much better to get Staff of Flowing Water instead of Ardent Censer or at least before you get Ardent Censer. It all comes down to drafting and which items and plays are best.

You should also put Vision around areas where your carries are. If your carry for example if its the Hecarim, and he has been ganking Mid lane all game, and tends to play towards Mid lane, put more vision around mid lane to set up for safer and more secure ganks and you can perhaps roam with your carry now that you know you won't get caught out in the area since there is vision. Playing around vision and your carries is important.

How do I fight for objectives with Yuumi?

Fighting for objectives as Yuumi is mostly like any support. The first thing you should do (and the easiest one) is to set up vision on the objective - let's say it's Hextech Dragon . Set up vision in the Pixel Brush which can be found on both sides of Summoners Rift , to the side of each Dragon and Baron Nashor / Rift Herald pit. Along with vision around and behind the Dragon pit. The same would go for any other objective, like if there is an Objective Bounty on the first Mid lane tower , or the Rift Herald .

After this, you can sit in a Brush as I mentioned in the Early Game portion of the guide, - this trick works at any part of the game but can give easy and accessible kills early game as well - with an ally, you can use your Final Chapter to cheese the enemies and catch them off guard, and if there is a big objective, maybe kill the entire enemy team. This trick works most of the time if all 5 teammates are in one brush but make sure to use a Control Ward before trying to use this trick. Make sure to ping back your allies with this Ping(if you dont know how: using G/V keys, you press the corresponding ping key and click on a target. For example if you press V (retreat) and then on an enemy champ it will ping "fall back from..." while pressing G and then on an enemy champ will ping for target/assist.) If they are trying to do the Dragon / Baron Nashor / Rift Herald in the pit and the enemy team is likely behind the Dragon / Baron Nashor / Rift Herald Pit - to tell them to walk back a bit and pull the Dragon / Baron Nashor / Rift Herald back a little so that the enemy jungler (or whoever would try to steal the objective) can't steal the objective as easily.
This is just basic knowledge, but it is very important for setting up to do objectives.

How should I play teamfights when playing Yuumi?

Teamfighting is very special for Yuumi because she is the most unique champion in the game - There is no champion that has her playstyle. So it will take a bit of time to fully grasp her playstyle and how she is meant to be played.

The first thing is to prioritize your carry. Yuumi is useful only with an allied champion nearby, because of all of her abilities being reliant on using You and Me!
You should be switching from ally to ally in teamfights trying to angle your Prowling Projectile at maximum range and cast time to get the empowered version - as said in the Abilities section of the guide, Yuumi's Prowling Projectile range can be extended by using You and Me! on another ally, as it changed the range of the ability overall, but the cast duration is still the same unless you hit a target. - this is very important because it maximizes your damage and allows Prowling Projectile to slow, which catches enemies out very easily.
Your Ultimate ability, Final Chapter is insane in teamfights as well and uses the same range mechanic as You and Me! because it can be casted while using You and Me! to reposition it to help get each and every Enemy Champion rooted by Final Chapter.
Zoomies is a game changer in teamfights, and you should be using it only when your ally has missing health for the most part - unless you will not need it again in the fight and you are chasing one or two enemies down. Prioritize using Zoomies on allies that utilize it's Attack Speed and Movement Speed bonuses.
Using Bop 'n' Block to make sure Yuumi doesn't run out of Mana is very important too. Make sure that before you detach from You and Me! to use Bop 'n' Block, there is no enemies nearby that have any immobilizing Crowd Control spells that can be used on you to cancel your You and Me! animation when attaching back onto an Ally Champion.


Overall, Yuumi's mid and late game is incredibly strong. Yuumi scales really well into the late game with her items and levels, being able to output insane healing and shielding for her team and damage in all fights.

Thank you
