Without Master (Ex)
At 8th level, the ronin’s fierce independence allows him to overcome staggering odds. The ronin can summon up this willpower as an immediate action, and can use it in one of three ways. He can use his willpower whenever an attack would reduce him to fewer than 0 hit points but wouldn’t kill him, to instead be at 1 hit point and conscious. He can use his willpower after making an attack roll to confirm a critical hit in order to reroll the confirmation roll. Finally, he can use his willpower to take 10 on a skill check during combat, even if the situation or the skill would not normally allow him to take 10. A ronin can use this ability once during a combat.
