Maddening Obliteration

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 %1) to negate this effect.
