Intellect devourer

Intellect Devourers are small creatures in the world of Critical Role, Dungeons and Dragons, and Pathfinder.

Creature Information
Intellect Devourers resemble brains with four legs similar to most animals. They reside deep in the Underdark with the Illithids

They seem to act as some sort of pet or extensions of Illithids, whether or not they are Illithid creations or they naturally reproduce in the world of Critical Role is unknown.

During the events in the Underdark with Vox Machina, an Intellect Devourer turned Grog into a vegetable with one attack due to the barbarian's low intelligence score of 6. They also accompanied the Illithid party that entered the Elderbrain Temple in Yug'Voril that Vox Machina was forced to fight.

Abilities
While Intellect Devourers easy to kill, they can easily cripple any individual with a low intelligence.
