Upon dying, Kog'Maw starts a chain reaction in his body which allows him to continue moving (but not take any other action) and causes him to gain up to 40% movement speed gradually over 4 seconds. At the end of this duration he detonates, dealing 100 + (25 × level) true damage to surrounding enemies.
