Yorick Ability (LoL): Mourning Mist

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

All enemies hit by the globule are slowed by 30% for 2 seconds and champions and monsters are marked for 4 seconds.

Yorick, his Mist Walkers, and the Maiden of the Mist gain 20% bonus movement speed when moving towards marked targets, and Mist Walkers that were near an affected champion gain the ability to leap to them on their next attack.
