Defiant

You never say die. You keep trying even when you fail in front of an enemy, which can sometimes turn failure into success.

• Whenever you roll a 1 on an ability check, attack roll, or saving throw in combat, you can roll the d20 again. If the roll had advantage or disadvantage, you can reroll only one die and it must be one that rolled 1. You must keep the new roll, even if it is a 1.
