Using this technique, the user uses his bloodline to extract his bones to a greater degree than with any of the previous dances. Out of everywhere on his body, forearm, hands, ribs, back, shoulder and even his legs, the bones stick out in a protective and lethal armor.

He gains a +3 natural armor bonus to defense, and all attacks made against him with a hand-held weapon of Small or smaller size or unarmed attacks deal 10 points of piercing damage to the attacker in return. In addition once every 3 rounds, he may give up all his attacks for the round in order to spin wildly and make an attack against all adjacent opponents, as per Whirlwind Attack feat.

All unarmed attacks made in this state deal damage as though attacked by a claw attack of a creature one size category larger than the user.
