Combat

Improved Grab (Ex): To use this ability, a gorynych must hit an opponent one or more size categories smaller than itself with a tail whip attack. If it wins the grapple check, it establishes a hold and uses its tail wrap attack. Against human-sized opponents, a gorynych usually chooses to grapple only with its tail to avoid being grappled itself, thereby reducing its grapple bonus to +13.

Rake (Ex): If a gorynych hits a grappled foe with all three bite attacks, it can rake with its claws. Attack bonus +23 melee, damage 2d8+4.

Rend (Ex): If a gorynych hits with two bite attacks, it latches onto the opponent's body and tears the victim apart like a wishbone. This attack automatically deals an extra 4d8+13 points of damage.

Tail Wrap (Ex): After a successful grab, a gorynych can attempt to wrap its opponent with some or all of its remaining tail whips with a single grapple check. Each tail whip beyond the first reduces the penalty for grappling without being grappled by -4. Thus, a gorynych with three tail whips wrapped around a foe has a grapple modifier of +21 (+33, -20 for choosing not to be grappled, +8 for two extra tail whips).

Skills: Because of its multiple heads and keen senses, a gorynych has a +4 racial bonus on Listen and Spot checks.
