Whenever Cho'Gath kills a unit, he recovers 17 + (3 × level) health and 3.25 + (0.25 × level) mana.
COST: 90 mana
Active: Cho'Gath stamps the ground, causing a 175-radius target location to tremble for 0.625 seconds. Afterwards, spikes erupt from it, dealing magic damage to and knocking up all enemies hit for 1 second. Targets hit are slowed by 60% for 1.5 seconds after landing.
Toggled abilities do not count as ability activations for the purposes of effects such as Spellblade or Force Pulse.
The width of the projectile scales with Cho'Gath's size, and will also factor in external size modifiers such as Wild Growth and Storm Shield.
COST: 100 mana
Active: Cho'Gath devours target enemy, dealing true damage. If Feast kills the target, Cho'Gath grows larger and gains extra health and basic attack range, stacking up to six times. Cho'Gath loses half of these stacks, rounded up whenever he dies. (Lost stacks being rounded up, thus, kept stacks rounded down.)
Feast deals 1000 (+ 70% AP) true damage to minions and monsters.
