Sharpshooter

Attacking at long range doesn't impose disadvantage on your ranged weapon attack rolls.
* Your ranged weapon attacks ignore half cover and three-quarters cover.
* Before you make an attack with a ranged weapon that you are proficient with, you can choose to take a -5 penalty to the attack roll. If the attack hits, you add +10 to the attack’s damage.
