Yorick Ability (LoL): Mourning Mist

Yorick hurls a globule of Black Mist that splashes across an off-centered area at the target location, dealing 15% of target's current health magic damage to all enemies within the area, down to a minimum threshold of 70 / 105 / 140 / 175 / 210 (+70% of ability power).

Enemy champions and monsters hit by the Black Mist are slowed by 30% for 2 seconds, and are marked for 4 seconds, during which they take 40% bonus damage from 8 attacks by Mist Walkers and continuously raise a Mist Walker from each nearby grave, up to a maximum of 4. Yorick, Mist Walkers and the The Maiden gain 20% bonus movement speed when moving towards nearby marked enemies. Marked champions are also revealed.

Mist Walkers will leap to enemy champions and large monsters cursed by the mark, dealing 100% of their AD upon arrival.
