1 minute/stamina die
As an action, make a weapon attack to disorient the creature.
On a hit, add the stamina die to the attack’s damage and the creature must succeed on a Reflex saving throw or it can’t take reactions for the duration.
On a critical hit, add twice as much damage.
On a miss by 4 or less, add half as much damage.
The creature can repeat the saving throw at the end of each of its turns, ending the effect on itself on a success.
