As a bonus action when you hit a creature with a melee weapon attack that deals bludgeoning damage, you crush the target’s skeletal structure. The target must make a Fortitude saving throw.

On a failed save, add the stamina die to the attack’s damage roll and the target is slowed 1 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.

Enhance

You can increase the damage for each additional stamina die expended and the slowed level by 1 for every other additional stamina die expended.
