Abilities

Icathian Surprise

EFFECT RADIUS: 400

Innate: Upon taking fatal damage, Kog'Maw remains active for 4 seconds, becoming unable to basic attack, cast abilities, use summoner spells or activate items but also being invulnerable, untargetable, and immune to crowd control and gaining up to  40% bonus movement speed over the duration. At the end of the duration he explodes, dealing 125 − 550 (based on level)  true damage to all nearby enemies.

Notes

• Upon Death, Kog'Maw loses all status effects (inherently including crowd control effects) that do not inherently persist through death.
  • An example for a debuff that does persist through death is Brand's Blaze.
• Icathian Surprise's untargetability does not destroy in-flight projectiles.
• Resurrection will take precedence over Icathian Surprise.
• After Icathian Surprise ends, the corpse of Kog'Maw will retain unit collision for the duration of his death animation.
• Icathian Surprise will still trigger if Kog'Maw is killed by the Nexus Obelisk.
• If Kog'Maw has an auto attack in the air at the same time that he's moving while he dies, as long as the auto hits the target after Icathian Surprise has started Kog'Maw will be able to auto once during Icathian Surprise.
• Kog'Maw's usable summoner spells will be placed on a 5 second cooldown upon becoming a zombie.
• During Icathian Surprise, Kog'Maw's attack range is reduced to 0, making him automatically path near enemies he is trying to target.
