Recent Patch Notes That Apply To Yuumi


Spellthief's Edge:
Ability Power: 8 ⇒ 10
Health: 10 ⇒ 25

Summon Aery:
Adaptive Damage: 10-40 (based on level) (+15% bonus AD) (+10% AP) ⇒ 10-50 (based on level) (+10% bonus AD) (+5% AP)
Shield: 30-75 (based on level) (+35% bonus AD) (+22.5% AP) ⇒ 30-100 (based on level) (+10% bonus AD) (+5% AP)
Feline Friendship P:
This is Yuumi's Passive, when off cooldown hitting an enemy champion with an ability or a basic attack will heal her or an ally if she attaches to them within 4 seconds of proccing her passive. While her passive is off cooldownm Yuumi'snext basic attack gains 50 bonus range and has an uncancelable windup making it easier to procc using a basic attack.

While attached to an ally Yuumi grants them 2 permanent Friendship Stacks whenever they kill a enemy champion or minions. The ally with the most Friendship Stacks becomes Yuumi's bestfriend, this empowers her abilites with additonal effects while she is attached to them.

Prowling Projectile Q:
This is Yuumi's main damage & the second way to procc the heal from her passive. Yuumi shoots a missile in the target direction that deals magic damage to the first enemy hit. If the target is a champion, they are also revealed and slowed by 20% for 1 second. If Yuumi uses this ability while attached to a champion she can steer the missile for a short period of time after that the missile accelerates in its current direction to deal increased damage and apply a stronger slow against champions that decays to 20% over 2 seconds.

Best Friend Bonus Q:
Prowling Projectile always applies its enhanced slow against champions and hitting a champion grants her Best Friend bonus magic damage on-hit for 5 seconds, increased by 0% − 75% based on your attached allies critical strike chance.

You and Me! W: This is Yuumi's way to attach to allies, Yuumi can hop between allies as often as she wants with out any cool down, if you hop to the ground You and Me! will be on cooldown. Any immobilizing effects cause W to go on a 5 second cooldown. While in team fights try to focus on your Best Friend as to procc the additonal effects. While attached Yuumi is untargetable, though can still die if any form of tic damage has been applied like poision or ignite. While hopping onto an ally Yuumi can be knocked out the air if any form of crowd control hits her.

Best Friend Bonus W:
Yuumi gains heal and shield power if attached to her Best Friend scailing with their level while her Best Friend gains healing on hit.

Zoomies E: This is Yuumi's shield, Yuumi grants herself a shield and gains bonus attack speed for 3 seconds, she also grants herself movement speed while the sheild is active. If Yuumi attaches to a ally these buffs will be applied to the ally instead of Yuumi. Additionally, she will restore mana to the ally based on the allies missing mana.

Final Chapter R: This is Yuumi's ultimate, it channels for 3.5 seconds shooting 5 waves in the target direction. Yuumi can steer the direction of the waves if initially cast while attached. Detaching causes her to lose this bonus for the duration of the ability. Allied champions hit by waves are healed, with each heal beyond their max health being converted into a shield. Enimes hit by waves take magic damage and are slowed by 10% for 1.25 seconds. This stacks and refreshes on subsequent hits, up to an effectiveness of 50%. Subsequent waves on enemies hit deal 25% damage.

Best Friend Bonus R:
Final Chapter's heal to the Best Friend is increased by 130%.
What To Build
13.23 Build
This build will scale the best in the current patch allowing for high amount of healing & shielding. It will also buff your allies the most allowing for both you & your team to snowball. It is also very cheap build compared to the other ones listed.

Heal & Shiled
Yuumi is made to scale with Heal & Shield items making this the "normal" build for her. This is also the cheapest build as it is made up support items which are cheaper as supports have less gold due to not killing minions. This build is the safest option as 99% of the time going to be able to afford it and it will always work well.

Full Ability Power
Though Yuumi is a enchanter meaning she scales with Heal & Shield power and her abilities scale with Ability Power. This means that when building AP you will scale your healing, shielding, and damage. The downside of this build is that it is more expensive so during difficult games you can fall behind fast if you are not earning enough gold.

Building boots is not a traditional thing to do on Yuumi Though Since Yuumi's rework Pro's & High Elo players have been building boots on her!

Ionian Boots of Lucidity: Build these to lower the cooldown of her passive as to be able to use the heal from it more often, it also helps with giving a little more movement speed as Zoomies does not give as much movement speed as it used to pre rework.

Sorcerer's Shoes: These are best for the magic penetration when building her full ability power as you are scaling into damage with this build.

Berserker's Greaves: These are best when building full attack speed.

Mythic Option's
Shurelya's Battlesong:This is the best mythic to build in my opinion right now. It gives bonus move speed that has been lost since the Yuumi Rework.

Moonstone Renewer: This is a good replacment mythic if you feel you need more healing for multiple allyies than engage.

Echoes of Helia: This is the best option to build if you are a more agressive enchanter and want to be able to mass heal one ally.

Everfrost This is best to build of a full AP build, it also is very good if you need some extra crowd control as it is easy to hit while attached to a ally.

Navori Quickblades: This is best when builing attack speed, it works by reducing the cooldown on your sheild which is needed for this build to work.

Situational Items
Void Staff: This items is the best option for a ability power scaling shampion to take as Anti Tank.

Chemtech Putrifier: As a enchater support this is the best anti heal item you can take.

Knight's Vow: Is useful for giving extra sustain to your hard carry but is only worth it if someone is hyper carrying the game.

Mikael's Blessing: Good for playing against crowd control heavy teams.

Mejai's Soulstealer: If you are expecting a really good game and want to heal for more and do more damage this is a good item to take early game. Taking dark seal on your first back, building mythic then Mejai's.

Redemption: This item is great for extended team fights & also helping out allies that are to far away from you. If you are finding there is a ally that keeps dying before the team can get to them or you need just a little more AOE healing this is a great pick.

Mortal Reminder: This is anti heal for the attack speed build only.
Laning Phase
During laning phase the most important thing is proccing your Feline Friendship to heal your ADC when needed and using Zoomies to block incoming damage. If you want to procc Feline Friendship with a basic attack instead of Prowling Projectile, you have to make sure all crowd control from the enemy team has been recently used to avoid putting You and Me! on a cooldown.

If your ADC is loosing lane the best thing to do is play safe and make it out of laning phase. Once you are out of laning phase, go to whoever is carrying your game or the jungler to help with ganks. Though this can mean you are no longer proccing your Best Friend Bonus as you will need to give it time to move onto the ally you are now with. This means sometimes it is better to stay with your ADC and ask for help from your allies.
How To Play Against CC
As a Yuumi any form of crowd control is a massive threat due to your slow move speed and it causing You and Me! to go on cooldown. If you want to hop off to procc Feline Friendship's heal or do anything wait until the nearby enemies have used their crowd control. If you know their root, hook, stun etc. is stopped by minions, then stay behind minions at all times while not attached to an ally.

Building Mikael's Blessing allows you to remove CC from your self and allies and can be a life saver in needed situations.
Getting vision for your team is an important part of being a good support, though as Yuumi this can be difficult due to your move speed and the danger of being caught alone. If you are going to ward, make sure you can see everyone on map or have a very good idea of where they are to minimize the danger.

At the start of the game take your Control Ward and take it to the buff your jungler is not taking, this allows them to know if they are being invaded. Once you have done that head to your jungler and place a Stealth Ward in pixel bush or tri bush to allow vision as they take their first camp.

If you are red side of the map & your jungler is starting at blue buff, you can also place your Stealth Ward over the dragon pit wall into the bush.

You can also use You and Me! to jump on your jungler to bot side buff and place a Stealth Ward in tri bush or pixel bush depending on where they dont place one. Keeping your Control Ward for jungle bush when you go to lane or to deny vision if the enemy team ward or attempt to invade.

On your first back exchange your Stealth Ward for Oracle Lens and buy 1-2 Control Wards this will allow you to set up for first drake.

While attached to a ally you can still use Oracle Lens and place wards this is useful to know.
Who To Sit On
Learning who to sit on and when is a important part of playing Yuumi and getting good at her, as it can make a huge difference in certain situations.

It is best to be on your Best Friend as to procc your Best Friend Bonus. Your ADC is most likely going to be your Best Friend, though sometimes situations call for you to leave them.

During laning phase if your ADC has left for any reason and you are not needed in lane, you can leave to either make a solo lane 2v1 or go to your jungler and help them with a gank until you are needed back in lane. While doing this, you need to be aware of your own lane, how the wave is doing and what the enemy ADC & Support are doing as you do not want them getting uncontested minions or taking tower. Along with this, an empty bot lane also allows them to roam so learning wave control to stop them from doiong this is important.

After laning phase the best person to go to is either the ally whoever is carrying or a lane that needs help (though if helping them will end up in you dying it is not worth it and you should go back to the carry). You can also go on the jungler if they are doing well to help with ganks, objectives and vision control.

During team fights you want to be on the carry for the most part though you do want to hop from person to person healing, keeping your team alive. Never go on a ally who has a ability that makes them invunruable as your time could be better spent healing other allies.
Who Should I Ban
The biggest counter for Yuumi is Leona, though her play rate can be very low so it can feel like a wasted ban. If you are struggling with keeping track of hook champion's cooldowns the best ban is the hook champion you struggle to agasint the most.

Mordekaiser is also a good ban due to playing with or against one can be a danger due to how his ultimate Realm Of Death works. If he catches you detached and uses his ultimate Realm Of Death on you it is an easy kill for him. Though he can also use his ultimate Realm Of Death on who you are attached to during a team fight meaning you are dropped in the middle of it and most likely going to die. On the other hand, if he is on your team being attached to him once he is past lvl 6 is very risky for Yuumi. While you can give sustain and use your Final Chapter to allow him to get kills very easily, as soon as Mordekaiser uses his ultimate Realm Of Death Yuumi will detach leaving you in a possible vulnerable position with no ally to jump to.

Taliyah is also a good ban due to most of her abilites being a form of crowd control. This can make it very hard for Yuumi to You and Me! to allies as it will stop her mid-air and put You and Me! on cooldown.
Tips 'n' Tricks
. Yuumi can block Caitlyn's ultimate Ace In The Hole if it is locked onto who she is attached to by simply detaching, This will place you directly in the way of it locking the damage and allowing you to hop back on.

. Yuumi can use Everfrost while attached to an ally. This can be a great follow up to Final Chapter or can be used while Final Chapter is in effect to root enemies who have managed to avoid it or have just arrived.

. If you are using Summon Aery pay attention to where it is at all times and its cooldown so you can heal for more and buff you ally more often.

. Summon Aery proccs items like Ardent Censer & Staff of Flowing Water.

. Yuumi turns invisible when attached to allies who are invisible. For example, Twitch , Evelynn , Shaco & Akshan.

. Yuumi can use Everfrost while Kayn is using his ultimate on someone rooting them in place.

. Yuumi use Zoomies while Kayn is using his ultimate on someone just before he comes out of it to shield him.

. Kassadin does not gain stacks on Force Pulse from Yuumi casting abilities while she is attached to a ally.

. You and Me! does not count as an ability activation for the purposes of on-cast effects such as Sheen Spellblade.

. Yuumi can channel Eye of the Herald while attched.

. Jungle monsters agression transfers to the ally Yuumi attaches to.

. Yuumi will detach if you use Guardian Angel or Teleport but not if you use Zhonya's Hourglass, in this case she can still use her abilities.

. The summoner spell Heal scales with Heal & Shield Power

. The summoner spell Heal halfs all other heals applied for a 35s after use
