Combat

Dire jackals hunt alone or in mated pairs. Like ordinary jackals, they chase prey until it is exhausted, or work together to flank their opponents.

Trip (Ex): A dire jackal that hits with a bite attack can attempt to trip its opponent (+9 check modifier) as a free action without making a touch attack or provoking attacks of opportunity. If the attempt fails, the opponent cannot react to trip the dire jackal.

Skills: Dire jackals have a +4 racial bonus on Jump checks. jackals have a +4 racial bonus on Survival checks when tracking by scent.
