You search one creature you can see within range for weak points with your magic, pointing them out to your allies. The target must make a Wisdom saving throw. On a failure, the target's weak points are exposed until the start of your next turn. When a creature hits the target with a weapon attack or unarmed strike for the first time on their turn, they may reroll the damage dice of their weapon or unarmed strike and use either total.
