1 minute/stamina die

As a bonus action when you hit a creature with a melee weapon attack that deals bludgeoning damage, you knock the target out. The target must make a Fortitude saving throw.

On a failed save, add one stamina die to the attack’s damage roll and the target and is incapacitated for the duration.

A creature can repeat the saving throw at the end of each of its turns, ending the effect on itself on a success.
