As an action, make a weapon attack and throw dirt, sand, or various debris into the eyes of a creature that you can touch or see within 2 meters. You must have sand in your hand to throw.
On a hit, add the stamina die to the attack’s damage and the creature must succeed on a Fortitude saving throw or it is blinded until the end of its next turn.
On a critical hit, add twice as much damage.
On a miss by 4 or less, add half as much damage.
You can augment this maneuver with the following options, expending stamina dice for each option.
You can increase the damage for each additional stamina die expended.
You can expend 2 additional stamina die so the creature is blinded for 1 minute/stamina die. At the end of each of its turns, a blinded creature can repeat the saving throw, ending the effect on itself on a success.
