As an action, make a melee weapon attack to render the creature unable to speak.

On a hit, add one stamina die to the attack’s damage and the creature must succeed on a Fortitude saving throw or it can’t speak 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.

Enhance

You can increase the damage for each additional stamina die expended.
