Stunning Critical

Your extensive training of melee weapons allow you to momentarily stun your opponent. You gain the following benefits:

• Increase your Strength or Dexterity score by 1, to a maximum of 20.
• Once per turn when you hit a creature with a critical attack using a melee weapon, you can forgo the critical damage from the attack to attempt to stun the creature. The target must succeed on a Constitution saving throw or be stunned until the end of your next turn. The DC for the Constitution saving throw is 8 + proficiency + the weapon damage dealt.
