Thanks to extensive practice with the crossbow, you gain the following benefits:
- You ignore the loading quality of crossbows with which you are proficient.
- Being within 5 feet of a hostile creature doesn’t impose disadvantage on your ranged attack rolls.
- When you use the Attack action and attack with a one handed weapon, you can use a bonus action to attack with a hand crossbow you are holding
- You have advantage on sneak attacks using a crossbow
-
- Attacking at long range doesn't impose disadvantage on your ranged weapon attack rolls.
- Your ranged weapon attacks ignore half 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 that attack hits, you add +10 to the attack's damage.
