Shoot First

Deadeye Technique: 11th, 13th, and 17th level You have learned that the person who shoots first is often the one who walks out alive. When you make a ranged weapon attack against a creature that has not yet acted during your first turn in combat and you have advantage on the roll, you can reroll one of the dice once. Additionally, on a hit, you deal an extra 1d8 damage of the same type as the weapon. This damage increases to 1d10 at 13th level and 1d12 at 17th level.

Granted by Deadeye Technique at 17th level.
