Trip (Ex): An advanced worg that hits with a bite attack can attempt to trip the opponent (a +11 check modifier) as a free action without making a touch attack or provoking an attack of opportunity. If the attempt fails, the opponent cannot react to trip the worg.
Author's note: This is a worg advanced just enough to be large sized, so that it can be a mount for hobgoblins and bugbears. I use the Warg rider minatures from GW's LoTR battlegame to represent them.
