Thinking on the Brecht main hand/offhand fighting style of rapier and main-gauche, there aren't really any Battlemaster maneuvers that specifically address that style. For purposes of my Brecht 5E campaign I'm tentatively introducing two new Battlemaster Maneuvers:

Parrying: A character equipped with a rapier and main-gauche adopts a stance to focus his/her offhand on parrying attacks. The character counts as having a shield for Armor Class benefits for this turn.

Main-Gauche Attack: A character equipped with a rapier and main-gauche adopts an aggressive stance, attacking with both rapier and main-gauche.Expend a superiority die and roll a normal attack with the rapier - if the attack hits, character treats the Raouer as a light weapon for this turn. Add the bonus damage to the main-gauche if it hits.

Thoughts on this? This allows non-Battlemaster Fighters to learn the fighting style with a feat. Any adjustments to the wording or rules that you think would benefit or better fit the fighting style?
