Grick

Gricks are monstrosities that have been encountered in the Underdark.

Description
The gricks encountered by Vox Machina resemble large bluish-and-purple worms with beaks, and four small tentacles that surround their mouths. They are very fast and seem to sense movement.

Abilities
Stone Camouflage: Advantage on hiding in rocky terrain.

History
Vox Machina encountered five gricks in a cavern where there was a thin boundary between the Material Plane and parts of the Far Realm. They were destroyed almost immediately using a combination of Tiberius's Fireball spell and Percy's homemade bomb.
