Disarming Strike (1 Ki Point). After making an unarmed strike, Yasuke can force the target in the same attack to make a DC-14 Strength saving throw or be disarmed on a fail. The weapon lands a number of feet away from the player equal to the roll of a D12, the direction being decided upon by a D6 (1 being north, following clockwise).

Redirect Weapon (1 Ki Point). If Yasuke is hit by a melee attack, he can reduce the damage taken by 1d10 + 10. If he reduces the damage to 0, then he can redirect the attack to another enemy target within 5ft of him. The new target takes the full damage of the enemy attack. The new target must be within 10ft or less of the original attacker.

Deflect Missiles. If Yasuke is hit by a ranged weapon attack, he can reduce the damage taken from it by 1d10 + 8. If he reduces the damage to 0, then in the same reaction he can expend 1 Ki Point to make a ranged weapon attack with the missile.
