i am working on a feat for the flavor of a Close Quarters combatant who gets inside the reach of their opponent's weapon and strikes weak points with a small weapon for extra damage. the basic idea was inspired by classic knife fighting and other forms of close quarters combat and is designed for tight spaces. i really don't want to give up the Sharpshooter/Great Weapon Master Benefit though but i need something to keep it valuable.
the original feat had a third benefit in the middle, but the benefit was too potent and too questionable in when it applied.
