Dazing Blow (Ex): The force of both of a cave troll's claws hitting can be overwhelming. If a cave troll hits with both claw attacks, the opponent must make a DC 22 Fortitude save or be dazed for 1 round. The save DC is Constitution-based.

Improved Grab (Ex): To use this ability, a cave troll must hit with its bite attack. It can then attempt to start a grapple as a free action without provoking attacks of opportunity.

Pounce (Ex): If a cave troll charges a foe, it can make a full attack, including two rakes.

Rake (Ex): Attack bonus +11, damage 2d6+7. A cave troll that gets a hold can make two rake attacks with its hind legs, including adjustment for Power Attack feat.

Rend (Ex): If a cave troll hits with both claw attacks, it latches onto the opponent's body and tears the flesh. This attack automatically deals an additional 4d6+13 points of damage.

Skills: *Cave trolls gain a +4 racial bonus on Survival checks when tracking by scent.

Cave trolls are brutal, instinctive hunters. They charge into melee combat, using their pounce and rend abilities on the nearest target.

A cave troll normally attacks using its Power Attack feat, taking a -3 penalty on its attack rolls and gaining a +3 bonus n damage rolls.
