Lycanthropes in their natural forms use whatever tactics are favored by their people, though they tend to be slightly more aggressive. Lycanthropes in animal or hybrid form fight like the animal they resemble.

Werewolves can assume a hybrid form as well as an animal form. In hybrid or wolf form, they can trip just as normal wolves do.

Alternate Form (Su): A werewolf can assume a bipedal hybrid form or the form of a wolf. The bipedal form is about 6 feet tall, with a short tail, and covered in fur. The legs are like those of a wolf and the head combines humanoid and lupine features in degrees that vary from one werewolf to the next. The animal form is that fully grown wolf without any trace of human features.

Trip (Ex): A werewolf that hits with a bite attack attempt to trip the opponent as a free action without making a touch attack a provoking an attack of opportunity. If the attempt fails, the opponent cannot react to trip the werewolf.

Skills: A werewolf in hybrid or wolf form gains a +4 racial bonus to Survival checks when tracking by scent.
