Hulks are large creatures found in the Summit Of The Sages, Frostblight Mill, and the Citadel of Shadows. They are related to the Grimkin and three Hulks are normally encountered at once. Despite their huge sizes, they're not too much of a hassle to take down.
Hulks are completely hairless, have green eyes, and big mouths with two sharp teeth on the bottom jaw. They have huge arms each with three fingers, and tiny legs. Their huge arms are likely the reason why it walks on all fours, like a gorilla.
