Hi! I'm Headsh0t1111 (EUNE). I've been playing LoL since s2. My first account was d4, but I quit LoL, and 1 years later, I started this account. When Yuumi came out on PBE, i fell in love with her playstyle. I'm not a master of the champ, but I love her so much, and I know how to play her. I hope that I can help you with this little guide. Have fun!

Pros:
- Very mobile
- Nice amount of healing
- Untargetable
- Fun to play
Cons:
- VERY squishy
- When her anchor dies, she probably dies too
- Worthless when alone

Jhin is very good with Yuumi. You can protect him while he is using his ult and clear his way.
Kog'Maw is good with Yuumi too, because he needs to stand still to do a lot of damage, and Yuumi can protect him, so he can kill everyone.

Braum , Blitzcrank and Nautilus are very good AGAINST Yuumi. They have a lot of CC, and if they hit you with only 1 ability, you are probably dead.

Summon Aery Aery works very well with Yuumi, because your W is activating it, and that makes Yuumi really powerful.

Manaflow Band You need Manaflow Band, because you need mana to harass the enemy botlane.

Celerity You need Celerity because your E gives you a burst of movement speed, and this rune buffs it.

Gathering Storm You have to stay alive at the end of tha game, so you need Gathering Storm, because it gives you adaptive force through the game.

Biscuit Delivery It gives you sustain, because it gives you mana and HP over time.

Cosmic Insight It gives you more CDR, and the CDR is always good.

PASSIVE: Yuumi periodically empowers her next basic attack against an enemy champion to restore 40 − 160 (based on level) Mana icon mana and grant her a 80 − 360 (based on level) (+ 40% AP) Hybrid shield that lasts until it is broken.
While attached, the shield transfers to her Anchor.

Q: Yuumi fires an errant missile that deals Ability power magic damage to the first enemy hit. If the missile is in flight for 1 second, it deals increased magic damage and applies a decaying slow to enemy champions struck. While attached, Yuumi directs the trajectory of the missile instead for up to 3 seconds before fizzling.

W:
PASSIVE: Yuumi and her Anchor gain bonus attack damage or ability power (Adaptive) equal to a percentage of the other's highest stat. Additionally, Yuumi starts with a point in You and Me! and her Q instead has 6 ranks.
ACTIVE: Yuumi Dash dashes to an allied champion and attaches to them. While attached, Yuumi is untargetable except from turrets and follows her anchor's movement, losing the ability to basic attack but retaining the ability to cast (except movement spells).
ACTIVE - CHANGE OF PLAN: Yuumi can switch her Anchor at no cooldown, and will detach automatically if her anchor dies. If re-activated without a valid target, Yuumi will detach from her anchor and dash up to 250 units in the target direction, triggering the cooldown. The cooldown starts ticking down when you attach to the first ally.

E: PASSIVE: Yuumi periodically stores a Zoomies charge, up to 2 stored at once.
ACTIVE: Yuumi heals herself, with the base amount increased by based on target's missing health and the scaling amount increased by based on target's missing health, and gains bonus movement speed decaying over 2 seconds.
While attached, her partner is targeted by the ability instead.


R: ACTIVE: Yuumi Dash recoils X units in the opposite direction, after which Book launches 7 waves over 3.5 seconds, each dealing magic damage. Enemy champions hit take only 50% damage from subsequent waves, and when struck with three waves, they are rooted for 1.75 seconds.
Yuumi can move and cast both W and E during Final Chapter.

At early game, don't be agressive, and don't push to the enemy's tower. At ~10-15 minutes, you can start roaming or pushing. Until 10 mins, protect your adc and help him to get kills or farm. Be careful, because if your anchor dies, you probably die too.

At a teamfight, you should attach to the strongest champ on your team, and heal him/her. If he/she goes in, attach to the carry and heal him/her. If the tank is on low hp, go and attach to him/her, and heal him, then go back to the carry. Repeat this until the teamfight ends. If the tank goes in, ult immediately.
