Intellect devourer

Intellect devourers are tiny aberrations associated with the mind flayers (illithids); as the name implies, their attacks target the mind.

Creature Information
Intellect devourers resemble brains with four legs that are similar to most animals'. They reside deep in the Underdark with the mind flayers.

They seem to act as some sort of pet or extension of illithids; whether they are illithid creations or they naturally reproduce in the world of Critical Role is unknown.

Abilities
While intellect devourers are physically weak, they can easily cripple any individual of low intelligence.


 * Devour Intellect - On a failed Intelligence saving throw, the creature takes 2d10 psychic damage; then, roll 3d6, and if the result is equal to or greater than the target's Intelligence score, the creature's Intelligence score is reduced to zero and it is stunned until it regains at least one point of Intelligence.

History
During Vox Machina's adventures in the Underdark an intellect devourer put Grog into a catatonic state with one attack due to the barbarian's already low intelligence score of 6.

Intellect devourers also accompanied the illithid party that entered the elder brain temple in Yug'Voril that Vox Machina was forced to fight.
