As a bonus action when you hit a creature with a weapon attack, you can blind the target by striking a sensitive area. The target must make a Fortitude saving throw.
On a failed save, add one of the stamina dice to the attack’s damage roll and the target is blinded for the duration. At the end of each of its turns, a blinded creature can repeat the saving throw, ending the effect on itself on a success.
You can increase the damage for each additional stamina die expended.
