In the Dungeons & Dragons fantasy role-playing game, the crucian is a monstrous humanoid.
The crucian first appeared in third edition in the Miniatures Handbook (2003). The crucian appeared as a player character race in Sandstorm (2005).
A crucian resembles an ugly, sad-faced, hunched, pointed-eared, brown in color humanoid with a lumpy, tortoise-like shell. They are always depicted with a blunt-spiked warhammer, and a protective leather head covering.
