Kog'Maw

the Mouth of the Abyss

Marksman

Mage

Lore

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. Though not inherently evil, Kog'Maw's beguiling naiveté is dangerous, as it often precedes a feeding frenzy—not for sustenance, but to satisfy its unending curiosity.
