Marksman

Thanks to extensive practice with the crossbow, you gain the following benefits:

• You ignore the loading property of firearms and Crossbows.
• 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 loaded firearm with the light property or a Hand Crossbow you are holding.
• Increase your Dexterity score by 1, maximum of 20.
• You gain proficiency with firearms (see “Firearms” in the Dungeon Master’s Guide).
