A cloaker can try to wrap a Medium or smaller creature in its body as a standard action. The cloaker attempts a grapple that does not provoke an attack of opportunity. If it wins the grapple check, it establishes a hold and bites the engulfed victim with a +4 bonus on its attack roll. It can still use its whip-like tail to strike at other targets. Attacks that hit an engulfing cloaker deal half their damage to the monster and half to the trapped victim.
