Maokai Ability (LoL): Nature's Grasp

Maokai summons a colossal wave of brambles and thorns, rooting enemies for 0.75 to 2.25 seconds, increasing with distance travelled, and dealing 150 / 225 / 300 (+75% of ability power) magic damage. Hitting a champion gives Maokai 40 / 50 / 60% movement speed, decaying over 2 seconds.
