Blade and Powder

Thanks to extensive practice, or maybe even sheer dumb luck. You have figured out how to dual wield a melee weapon and a one-handed firearm, you gain the following benefits:

• You gain proficiency with firearms (see “Firearms” in the Dungeon Master’s Guide).
• You ignore the loading property of firearms.
• 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 one-handed firearm that you are holding.
