Reincarnated Ridiculer

FEAT 5

You've practiced the art of taunting an enemy, ensuring they know death will only make you stronger. When you Demoralize an opponent, the target doesn't become temporarily immune to your attempts to Demoralize it unless you critically fail the check. If the target critically hit you with a Strike on its previous turn, the DC for this check is reduced by 4.
