Hamatulatsu Master

A hamatulatsu master replaces the normal monk bonus feats with the following: Deflect Arrows, Dodge, Exotic Weapon Proficiency, Improved Grapple, Intimidating Prowess, Scorpion Style, or Weapon Focus. At 6th level, the following feats are added to the list: Gorgon's Fist, Hamatulatsu, Improved Sunder, Mobility, Power Attack. At 10th level, the following feats are added to the list: Critical Focus, Impaling Critical (unarmed strike), Improved Critical, Medusa's Wrath, Snatch Arrows. At 14th level, the following feat is added to the list: Improved Impaling Critical. Anytime a hamatulatsu master would gain a bonus feat, she can instead choose to gain two additional uses of stunning fist per day.

A hamatulatsu master expands the conditions that she can apply to the target of her stunning fist beyond merely stunning her target. At 4th level, she can choose to make the target shaken for 1 minute. At 8th level, she can choose to deal 1d10 points of nonlethal bleed damage. At 12th level, she can choose to make the target frightened for 1d3 rounds. At 16th level, she can deal 2d12 points of nonlethal bleed damage. The shaken and frightened conditions allow the target to attempt a Will save to negate the effect instead of a Fortitude save. This ability otherwise functions as normal for a monk of her level.

By spending 1 point from her ki pool as a swift action, a hamatulatsu master can make one additional attack at her highest attack bonus when making a flurry of blows attack. Alternatively, she can spend 1 ki point as a swift action to gain one additional use of her stunning fist ability that round, though this does not grant her an additional attack. Finally, as an immediate action, a hamatulatsu master can spend 1 ki point to make a single melee attack with a +2 bonus against a creature that has damaged her with a natural melee attack, unarmed strike, or weapon without the reach property. This ability otherwise functions as normal for a monk of her level.

At 5th level, a hamatulatsu master gains immunity to all spells, spell-like abilities, and effects with the pain descriptor, as well as a +2 bonus on saving throws against effects that would sicken, nauseate, stagger, or stun her. This ability replaces purity of body.
