• 3Anti-heal on whoever hits the host — mandatory.
• 4Early 2v2s are 2v1: force them relentlessly.

• ✓Detached, she's the easiest kill in the game.
• ✓Heals crumble to Grievous Wounds.
• ✓Her lane phase is among the weakest.

Abilities & how to counter them

What each of Yuumi's abilities does — and how to play around it.

• P
  Feline Friendship

  Periodically, when Yuumi strikes a champion with an attack or ability, she restores health to herself and the next ally she Attaches to.While Attached, Yuumi generates a special bond with her allies. The ally with the strongest bond enhances Yuumi's abilities while she is Attached to them.

  Strong: periodic empowered autos restore her mana and shield the host. Weak: she must DETACH range to auto — that's your kill window.

• Q
  Prowling Projectile

  Yuumi fires a missile, dealing damage and slowing first target hit. It deals bonus damage and an enchanced slow if it takes at least 1.35 seconds to get to its target. While on her Best Friend, the slow is always enhanced and grants bonus On-Hit damage to her ally.While Attached, the missile can be controlled with your cursor for a brief period.

  Strong: a steerable slow-poke missile from total safety. Weak: slow and steered — its curve telegraphs; juke late.

• W
  You and Me!

  Yuumi dashes to a target ally, becoming untargetable from everything except turrets. While on her Best Friend, she gains Heal & Shield Power and grants her Ally On-Hit healing.

  Strong: attached she's UNTARGETABLE — zero risk support. Weak: attached she's also zero bodies — force 5v4 fights relentlessly.

• E
  Zoomies

  Shields Yuumi and boosts Move Speed and Attack Speed. If she's attached, she passes it to her ally instead.

  Strong: heals and hastes the host on a short loop. Weak: Grievous Wounds turns the loop into noise.

• R
  Final Chapter

  Yuumi channels five waves that damage enemies and heal allies. Yuumi can move, attach, and cast Zoomies! while channeling. While on her Best Friend, this spell also follows her mouse.

  Strong: rooting waves across the fight while attached. Weak: waves need stacking hits to root — walk OUT of the channel cone early.
