Yorick Ability (LoL): Omen of Pestilence

Yorick summons a Decaying Ghoul that arrives with a violent explosion, dealing 60 / 95 / 130 / 165 / 200 (+100% of ability power) magic damage and slowing nearby enemies by 20 / 25 / 30 / 35 / 40% for 1.5 seconds. While the Decaying Ghoul remains alive, nearby enemies continue to be slowed by 10 / 12.5 / 15 / 17.5 / 20%.
