Master of Arms

You have mastered weapons and can make attacks that others find impossible. You gain the following benefits:

• Attacking at long range doesn't impose disadvantage on your ranged weapon attack rolls.
• Your weapon attacks ignore half cover and three-quarters cover.
• On your turn, when you score a critical hit with a weapon or reduce a creature to 0 hit points with one, you can make one weapon attack as a bonus action.
• Before you make an attack with a weapon that you are proficient with and wielding with two hands, you can choose to take a penalty to the attack roll equal to your proficiency bonus. If the attack hits, you add a bonus to the attack's damage equal to twice your proficiency bonus.
