This animal can be any predator, scavenger, or omnivore whose size is within one size category of the base creature’s size (Small, Medium, or Large for a Medium base creature). Lycanthropes can also adopt a hybrid shape that combines features of the base creature and the base animal. A lycanthrope’s hybrid form is the same size as the base animal or the base creature, whichever is larger.
A creature with this special quality has the ability to assume one or more specific alternate forms. A true seeing spell or ability reveals the creature’s natural form. A creature using alternate form reverts to its natural form when killed, but separated body parts retain their shape. A creature cannot use alternate form to take the form of a creature with a template.
