Driders are sexually dimorphic. A female drider's lower spider body is sleek and graceful, often similar to a black widow's body, while its upper drow torso retains its alluring curves and beautiful face (with the exception of sharp, poisonous fangs). A male drider's lower body is bulky like a tarantula, while its upper body is wiry and bears a hideous face more spider than drow, complete with fanged mandibles.
