When you clobber an opponent with your fists, you inundate its mind with visions of madness and horror.

Prerequisite(s): Wis 15, Cha 11, Improved Unarmed Strike, Stunning Fist, Knowledge (arcana) 4 ranks, ki pool class feature, nongood alignment.

Benefit(s): When you damage a living creature with an unarmed strike while using Maddening Style, and you have at least 1 point in your ki pool, that creature suffers a –2 penalty on saving throws against any confusion, madness, and insanity effects (including your Maddening Strike) for 1 round. Additionally, if you reduce a creature to fewer than 0 hit points with a Stunning Fist attack, you can spend 2 points from your ki pool as a free action to obliterate your opponent, reducing their body to fine dust as per disintegrate. A living creature can attempt a Fortitude save (DC = 10 + 1/2 your character level + your Wisdom modifier) to negate this effect.
