Improved Battle Master

Fighter Subclass Feat (Prerequisite: Battle Master Fighter Subclass)

You focus much of your time and experience into the maneuvers you know. Whether this means working closely with your allies to agree on certain commands, or focusing on the way you yourself can alter a fight, you've improved your skills as a Battle Master, gaining the following effects:

• You learn 1 extra maneuver of your choice.
• You regain a superiority die anytime you use Action Surge or Second Wind.
• When rolling a superiority die, you can choose to expend an extra superiority die to reroll that number, taking the larger result.
