Duel Wielding Master

You must have Duel Wielder feat, and at least 3 levels in fighter or barbarian

When you choose to attack with your offhand weapon as a bonus action, you may make 2 attacks instead of 1.

You may also make an additional attack during the same turn in which you action surge, as long as you take the attack action as the additional action.

You may make 1 melee attack as part of raging when you enter rage, as long as the weapon does not have the finesse property.
