Belched forth from a rotting Void incursion deep in the wastelands of Icathia, Kog'Maw is an inquisitive yet putrid creature with a caustic, gaping mouth. This particular Void-spawn needs to gnaw and drool on anything within reach to truly understand it...
Upon dying, Kog'Maw starts a chain reaction in his body which causes him to move faster and detonate after 4 seconds; dealing 100 + (25 x lvl) true damage to surrounding enemies.
Kog'Maw launches a corrosive projectile which deals magic damage and corrodes the target's armor and magic resist for a short time. Kog'Maw also gains additional attack speed.
Kog'Maw's attacks gain range and deal a percent of the target's maximum health as magic damage.
Kog'Maw launches a peculiar ooze which damages all enemies it passes through and leaves a trail which slows enemies who stand on it.
Kog'Maw fires an artillery shell at a great distance dealing magic damage (increased significantly on low health enemies) and revealing non-stealthed targets. Additionally, multiple Living Artilleries in a short period of time cause them to cost additional Mana.
