Prerequisite: 4th level

Merciless Break - Active Ability (Attack)

When you take the Attack action on your turn, you can replace one of your attacks with inflicting a debilitating injury on a creature you are grappling.

• The creature takes 2d6 + your Strength modifier bludgeoning damage and suffers an injury for 1 minute. The number of d6 increases by one when your proficiency bonus increases (with the total number of d6 equaling your proficiency bonus). While suffering from this injury, the creature subtracts d6 from attacks and ability checks, and must pass a DC 10 Constitution saving throw to successfully cast a spell.
• The target creature makes a Constitution saving throw at the end of each of their turns, ending the effect of the injury on a success. A creature can spend their action treating their injury to automatically pass the saving throw.

• DC is 8 + your Strength or Dexterity modifier (your choice) + your proficiency bonus.

Once you use this feature, you cannot use it again until you complete a short or long rest.
