Senna Ability (LoL): Absolution

Senna can attack souls that spawn from dead enemies to absorb their Mist. She can also siphon Mist from enemy champions she hits with attacks or abilities twice, dealing an additional 1-16% of the targets current health as physical damage.

Each stack of Mist grants 0.75 attack damage. Every 20 stacks grant 20 attack range and 10% critical strike chance. 35% of any excess critical strike chance is converted into life steal.

Senna's attacks take extra time to fire, deal an additional 20% physical damage and briefly grant her 10 / 15 / 20% of the targets movement speed.

Senna can only siphon Mist from an individual champion once every 6-4 seconds. Souls only have a 2.7% chance to spawn from minions Senna kills. Souls always spawn from large minions Senna doesn't kill, champions and large jungle monsters. Senna does not gain any attack damage on level up and her critical strikes deal 8.5% less damage.
