Oppressive

You are unmatched when in a one-on-one competition. You gain the following benefits: 

-When making a contested ability check against another creature, you always have advantage regardless of any previous advantage or disadvantage. Also, creatures contesting against your roll have disadvantage on the check. 

-When you are hit by a melee attack, you can make a contested Constitution saving throw against the attack roll. On a success, you take half damage. You can use this ability a number or times equal to your proficiency bonus. You regain all uses on a long rest.
