Frontline Master 2

Your training and discipline have made you a formidable combatant on the frontline. Your enemies can barely move without facing punishment. When you use Action Surge, you gain the following benefits until the end of your next turn:

- When you make an Opportunity Attack, you can make an Extra Attack as part of the same reaction.

- When you hit a creature with an Opportunity Attack, that creature has disadvantage on attacks against you until the end of your next turn.

- When you score a critical hit on an Opportunity Attack, you gain an additional reaction. You can only gain this extra reaction once per round.
