Yuumi Ability (LoL): You and Me!

Passive: While on her Best Friend, Yuumi gains an additional 5 / 7.5 / 10 / 12.5 / 15% heal & shield power (depending on ally level) and her ally also restores 3 / 5 / 7 / 9 / 11 (+0.4% of ability power) health on-hit.

Active: Yuumi dashes to an ally champion and attaches to them. While Yuumi is attached, she follows her partner's movement and is untargetable except from towers. Immobilizing effects on Yuumi places this ability on a 5 second cooldown.

Cooldown: 10 / 5 / 0 seconds.
