Willful Defiance

You loudly proclaim your opposition to a single creature you're aware of within 60 feet. You gain a +1 circumstance bonus to Armor Class and saving throws against the selected creature’s attacks, spells, and other effects for 1 minute. During that time, if you would fail or critically fail a saving throw against the selected creature, you can choose to reroll the failed save. If you do, after rerolling, Willful Defiance ends.
