Yuumi recoils and opens Book, launching 7 waves of 60 / 100 / 140 (+20% of ability power) magic damage over 3.5 seconds. Enemy champions who are hit by multiple waves take only 50% damage from any wave beyond the first, and they are rooted for 1.75 seconds when struck by three waves.

During Final Chapter, Yuumi can move and cast You and Me! and Zoomies.
