Alistar Ability (LoL): Trample

Alistar tramples the ground, dealing 100 / 125 / 150 / 175 / 200 (+40% of ability power) damage over 5 seconds to nearby enemies, ticking every 0.5 seconds.

Every trample pulse that hits at least one enemy champion grants Alistar 1 Trample stack, capped at 5. At 5 Trample stacks, Alistar's next basic attack against a champion deals 40 (+15 per level) additional magic damage and stuns the target for 1 second.
