V9.10 - Added

• Bop 'n' Block (Innate)
  • Innate: Yuumi periodically empowers her next basic attack against an enemy champion to restore 30 − 160 (based on level) mana and grant her a 50 − 330 (based on level) (+ 40% AP) shield that lasts until it is broken.
  • While Attached, the shield transfers to her Anchor.
  • Static Cooldown: 20 − 8 (based on level) seconds.
• Prowling Projectile (Q)
  • Active: Yuumi fires an errant missile that deals 40 / 60 / 80 / 100 / 120 / 140 (+ 30% AP) magic damage to the first enemy hit.
  • If the missile is in flight for 1 second, it instead deals 60 / 100 / 140 / 180 / 220 / 260 (+ 60% AP) magic damage and slows by 30 / 40 / 50 / 60 / 70 / 80%, decaying over 1 / 1.1 / 1.2 / 1.3 / 1.4 / 1.5 seconds, to enemy champions struck.
  • While Attached, Yuumi directs the trajectory of the missile instead for up to 3 seconds before fizzling.
  • Mana Cost: 60 / 65 / 70 / 75 / 80 / 85.

Additionally, Yuumi starts with a point in You and Me! and Prowling Projectile instead has 6 ranks.
