Morgana Ability (LoL): Soul Shackles

Morgana chains herself to nearby enemy champions, dealing 175 / 250 / 325 (+80% of ability power) magic damage and slowing them by 20%. After 3 seconds, enemies unable to break the chains take an additional 175 / 250 / 325 (+80% of ability power) magic damage and are stunned for 1.5 / 1.75 / 2 seconds. While casting this ability, Morgana gains 10 / 35 / 60% movement speed towards enemies she has chained.
