Hello there, I'm Sky, a support main since season 7, and this is my first guide here. I've been playing Yuumi since season 9, for those who are wondering, and mained her since. I hope this guide will help you!
Yuumi is an enchanter support with a unique sort of playstyle, being able to attach to a teammate. This makes her more of an immense buff to the whole team or a certain fed teammate who can carry, rather than a champion like any other, so she might not be as easy as you would think at first.
Compatible with almost any ADC
High Sustain due to shields and heals
Shorter Recall timer because you can attach to a recalling teammate
Can disengage quickly If not CC'd
Great late game

Really bad early game (power spike at level 6)
Can't do anything by herself
Relies on at least one fed carry
An aggressive playstyle can be really mana-consuming
Very often banned, especially in higher elo
Squishy (when unattached)
Passive: Feline Friendship: Periodically, Yuumi's next basic attack against an enemy champion gains 50 bonus range and becomes non-projectile. This attack restores 25 − 100 (based on level) (+8% max mana) mana and grants her a 60 − 400 (based on level)(+ 30% AP) shield that lasts until it is broken.

While attached, the shield transfers to her Anchor.

[*] Notes regarding Bop 'n' Block:
The shield has an unlimited duration, therefore it can be charged way before a fight
You can use this most times when you are not in a dangerous position to recharge some mana

Q: Prowling Projectile: Yuumi fires an errant missile that deals 40 / 70 / 100 / 130 / 160 / 190 (+ 30% AP) magic damage to the first enemy hit. If the missile is in flight for 1 second, it deals 45 / 85 / 125 / 165 / 205 / 245 (+ 40% AP) (+ 2 / 3.2 / 4.4 / 5.6 / 6.8 / 8% of the target's current health) magic damage, and slows enemy champions struck by 20% for 1 second

[*] Notes regarding Prowling Projectile:
Your basic poke
Really mana consuming early, becomes way cheaper towards mid and late game
You can use You and Me! to extend the range of Prowling Projectile, by attaching to somebody closer to the enemy while the missile is flying.

W: You and Me!: Yuumi and her Anchor gain 12 / 14 / 16 / 18 / 20 (+ 12 / 14 / 16 / 18 / 20%) of the Anchor's adaptive force and a percentage of its attack damage or ability power, whichever is higher, as adaptive force. Additionally, Yuumi starts with a point in You and Me! and Prowling Projectile instead has 6 ranks.

20 / 23.33 / 26.67 / 30 / 33.33% bonus AD

12 / 14 / 16 / 18 / 20% AP

[*] Notes regarding You and Me!:
This is what makes Yuumi unique
You can tank for a bit (make sure you don't get CC'd) and attach safely for a bit of Sustain)
You can tank certain forms of CC, such as Zoe's sleep from her E, Sleepy Trouble Bubble, if you attach while still drowsy.

E: Zoomies: Yuumi heals herself for 40 / 45 / 50 / 55 / 60 (+15% max mana) and gains 15% (+ 10% per 100 AP) bonus movement speed and bonus attack speed for 3 seconds.

[*] Notes regarding Zoomies:
Really expensive early
Huge amounts of healing, AS and MS in late

R: Final Chapter: Yuumi and Book channel for 3.5 seconds, launching 7 waves over the duration each dealing 60 / 80 / 100 (+ 20% AP) magic damage. Champions hit take only 50% damage from subsequent waves, and when struck with three waves, they are rooted for 1.75 seconds.

[*] Notes regarding Final Chapter:
This is Yuumi's powerspike in the laning phase
Works really well with Zoomies due to the bonus MS
Control it by switching between allies
You can get off while using it if the ADC gets CC'd to ensure the root
Use your Q, Prowling Projectile, before Final Chapter, as you cannot do that during the ult and you will be able to use it again shortly after it finishes.

Early to mid game:

You're winning the lane:
Try to deep ward as much as possible. Also, ward the Dragon 's pit and watch out for ganks. Junglers with high CC are really dangerous against Yuumi. Positioning matters too, don't get CC'd under the enemy turret.

You're losing/playing really safely:
Ward the Dragon 's Pit and lane bushes, especially if against a Thresh, Blitzcrank or Pyke, as they can get you out of your turret. Call your jungler for help. If they actually come (wow, that's rare), you usually get off your ADC and help the jungler, as they are closer to the enemy and will also get focused most of the time.

Mid to late game:

You're winning:
Ward the objectives and buffs, they will try to focus Baron and Drakes in order to have a chance to win.

You're losing! Oh no!:
Watch the minimap. A LOT. You can buy Farsight Alteration to keep an eye on the objectives far from your base. Again, objectives are the most important in any game, and it's your job to have them warded at all times.
A good support doesn't help the ADC when unnecessary and goes to other lanes instead. Even Yuumi can do this, although it's pretty hard:

You should roam when:

Your lane looks safe (e.g. the enemy support and ADC recalled)
Your ADC recalled but you don't have to
You have great vision (on the river and Deep wards) and you know where the enemy jungler is
You know the enemies don't have vision where you're going
Your mid/jungler are fighting on the river and your help would be needed
When your jungler is trying to gank mid from bot side and you feel like you can't/won't do anything in your own lane, hop on them and gank 3v1


You should recall when:

Your ADC needs to buy a vital item (such as B. F. Sword) or has lots of money to spend
You've pushed the wave into the enemy turret
You can help another lane and not lose objectives
There is no risk of losing plates/the turret
You need to reset the lane
In close combat, if attached, try to make a semicircle between you and the target with Prowling Projectile to empower it and deal more damage (after 1 second).

If your ADC wants to take Teleport, try to convince them to use Barrier or Heal instead, as you can no longer Teleport with them back to lane since patch 9.24.

You should always look to engage after the enemy support misses a skillshot, as you have low chances to defeat them otherwise.

Note: This part of the guide is still in progress. Hasn't been updated for season 11 either.

Warding items

You will buy Spellthief's Edge 90% of the time, meaning whenever the enemy ADC and support are not EXTREMELY pressure-applying (e.g. Ashe + Blitzcrank) and you can poke and/or push the minion wave into the turret to proc the bonus gold. When it evolves into Shard of True Ice, the mana regen will definitely help you to take longer fights, especially after the E cost nerf in patch 10.13.

Relic Shield is the remaining 10% of match-ups (taking Spellthief's Edge 90% of the time), and I really only recommend this into really hard matchups to help freeze the lane better against the menacing engage tank enemy support. The only downside is the bonus Health Regen instead of Mana Regen, as 100% of it makes a huge difference mid-game. If you don't think you can poke, just take Relic Shield instead of inting the lane.

Control Wards are essential for denying enemy vision. Every time you go back and are left with 75 or 150 extra money, buy one or two of them, it won't hurt. Also, keep a spot in your inventory for your control wards, unless you can buy a full item. Until I am able to do so, I usually buy Elixir of Sorcery, as it doesn't occupy any slots.

Stirring Wardstone is your second warding item, which you unlock at level 13. Buy it. No exceptions as long as you are support.

You will ALWAYS want to take Oracle Lens after you get Frostfang or Targon's Buckler, as you simply do not need the free yellow trinkets anymore. 5 available wards at the same time seems like too much, so why not deny vision instead?

Mythic Items

Shurelya's Battlesong is a great snowballing item, as it lets your team to secure more kills using the given speed. If you're 100% sure you're winning, buy it.

Moonstone Renewer is your basic mythic item for any enchanter. There are no matchups in which this is not good at all and overall the most balanced item for Yuumi.

Imperial Mandate is okay in most matchups, as it helps your marksman kite better and not only that, as the bonus movement speed can be useful for anyone. Pretty good Mythic Item in my opinion when you don’t need as much healing.

Liandry's Anguish is good on full AP Yuumi, but nothing else. Good against tanks.

Everfrost is good on full AP Yuumi, but nothing else. Good when you need a little more CC than usual, but would still recommend Liandry’s Torment against tanks.

Legendary Items

Ardent Censer is your other core item, which means you are taking it 99% of the matches. If you are running Summon Aery or have your shield passive, a little trick with this item is to go from ally to ally through all of them to proc the item's passive to everyone. Of course, pay attention to incoming CC while hopping from place to place.

Mejai's Soulstealer is another item which is really good especially on Yuumi, as her K/D/A ratios are very high in most games. Yuumi only dies after the whole team does (or at least she should), so if her team is not losing so bad, she can take it, as long as her K/D/A is above 5 (5 assists to 1 death).

Redemption is a very viable item on Yuumi, as most of the other items which provide bonus Healing & Shielding power. You usually take this in most losing situations, as the Item's Active really helps in teamfights and might turn a 5v5 around.

Mikael's Blessing is an extremely good item, I take it in most matchups as long as the enemy team have the smallest bit of CC. Its active is extremely good, cleansing any type of CC. ALWAYS take this vs Malzahar, Zoe, and other preventable single-target CC forms. Also, the 20% bonus Healing & Shielding is a lot, so it is good even without enemies like the ones listed above.

Morellonomicon only comes in hand in one case, and that is when their team has A LOT of health regen (e.g. vs Vladimir, Dr. Mundo, Soraka and Red Form Kayn, or at least 2 of these in the same matchup). Your R Final Chapter really comes in handy, as you can debuff the entire enemy team with Grievous Wounds, and if someone gets away, just Q Prowling Projectile them.

Is Knight's Vow underrated on Yuumi? I definitely think so. You can get faster to an ally after your previous anchor dies, but more importantly, you get to TANK some of the damage. You cannot possibly die from that, but it will help your team significantly. Now, tell me some damage mitigation to the otherwise invincible cat is not worth it. I take it vs fed AD assassins like Zed, Talon or Qiyana. Especially good against Zed because when he uses R Death Mark, you can get in front of all the Q Razor Shurikens, cancelling 40% of their damage, just be wary of CC.

Zeke's Convergence is really situational, just like Knight's Vow and Turbo Chemtank. I only take this one in the Yuumi + Garen botlane combo, as your icy Aura slows enemy champion running away from him, and his flame Aura helps his Q Decisive Strike and his auto-attacks.

Rylai's Crystal Scepter is a really off-meta item on Yuumi, but it can be at least decent paired with Liandry's Anguish because of the bonus burn damage towards impaired (slowed by this item) enemies. Works well with R Final Chapter, making enemies easier to catch. Again, viable when your team is full AD.
