Feline Friendship
Innate: Periodically, Yuumi's next basic attack against an enemy champion is empowered to have an uncancellable windup, gain 50 bonus range and become non-projectile. Upon hitting them with the basic attack or Prowling Projectile, or upon a Final Chapter hit on ally champions while You and Me!, the buff is consumed to heal her for (+ 30% AP). If she is You and Me! to an ally or does so within 4 seconds, they are healed for the same amount. Innate: While You and Me! to an ally, Yuumi grants them 2 permanent Friendship stacks whenever they kill enemy champions or minions. The ally with the highest Friendship stacks becomes Yuumi's Best Friend, which empowers her abilities with additional effects while she is You and Me! to them.

Q
Prowling Projectile
MagicActive: Yuumi fires an errant 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. You and Me! Bonus: Yuumi channels for up to 1.35 seconds to steer the missile at a slower speed. After being in flight for the same duration, the missile accelerates in its current direction for 0.5 seconds to deal increased damage and apply a stronger slow against champions that decays to 20% over 2 seconds. Feline Friendship Bonus: 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% / 7.5% (based on level).

You and Me!
Passive: While Yuumi is attached, she is untargetable (except by turrets and inbound projectiles) and casts her abilities from the Anchor's position, empowering them with additional effects. Active: Yuumi channels for 0.25 seconds, then upon completion dashes to the target allied champion and attaches to them upon arrival, designating them as her Anchor. You and Me! can be recast after 0.5 seconds of the attachment. Recast - Change of Plan: Yuumi detaches from her Anchor and dashes to the target allied champion to attach to them, refreshing the recast. She will detach automatically if her Anchor dies or under certain circumstances. If recast without a valid target, Yuumi will detach and dash 250-units in the target direction, placing You and Me! on a 0.25-second cooldown if it is not already on cooldown. Yuumi will be knocked down by any immobilizing or polymorphing crowd control during the dash to the ally. Yuumi starts with a skill point in You and Me! and Prowling Projectile instead has 6 ranks.

Final Chapter
MagicActive: Yuumi and Book channel for up to 3.5 seconds, during which they are ghosted, to launch 5 magical waves in the target direction. Allied champions hit by the waves are healed, with each heal instance beyond maximum health being converted into a shield that lasts for 1.5 seconds plus the remaining channel duration instead. Enemies struck by the waves take magic damage and are slowed by 10% for 1.25 seconds. The slow stacks and refreshes on subsequent hits, up to a total strength of 50%. Subsequent waves against enemies hit deal 25% damage. You and Me! Bonus: Yuumi can steer the direction of the waves if initially cast while attached. Change of Plan causes her to lose this bonus for the duration. Additionally, Feline Friendship can trigger from also hitting allied champions. Feline Friendship Bonus: Final Chapter's heal to the Best Friend is increased by .
