SQ demon lord traits


Clutch Foe (Ex)

If Kostchtchie chooses to use his hand to make a grapple check when he successfully slams and grabs a Medium or smaller opponent, he takes a –20 penalty on the grapple check. On following rounds, he can attempt to maintain his grapple on the creature as a swift action. If successful, he can constrict the creature for 1d8+28 points of damage, throw the creature (treat this as a bull rush), or use the creature as an improvised weapon. An opponent used as a weapon takes half as much damage as it deals to the creature it hits.

Crushing Blow (Su)

Once per round, Kostchtchie may designate any attack with his warhammer to be a crushing blow. He must designate this attack before making the attack roll. If he hits, the blow ignores the target's hardness and damage reduction, and allows him to make a free trip attempt against the target. This trip attempt does not provoke an attack of opportunity, can target a foe of any size, and has no chance of causing Kostchtchie to fall prone if he fails. A creature struck by a crushing blow must attempt a DC 44 Fortitude save; success means the creature is staggered for 1 round, and failure means it is stunned for 1 round and staggered for 1d6 rounds afterward. The save DC is Strength-based.

Favored Enemy (Su)

Against female giants or female humans, Kostchtchie's favored enemy bonuses increase to +8. Once per day, he can declare any one creature as a favored enemy, but only if that creature has damaged, humiliated, or otherwise inconvenienced him at some point in the previous 24 hours. His favored enemy bonuses against that creature last 24 hours.

Powerful Slam (Ex)

Kostchtchie's slam attack is considered a primary attack even when he uses a weapon in his other hand, and he always adds his full Strength bonus to damage dealt with his slam attack.

Vengeful Strike (Su)

Once per round, Kostchtchie may make an attack of opportunity against any creature that strikes him in melee combat. This attack of opportunity has a critical threat range of 18–20. Against female targets, the vengeful strike is also a crushing blow.
