Loading Weapon Master

• You gain proficiency with Firearms and Crossbows.
• You ignore the loading property of ranged weapons you are proficient in.
• Being Within 5 feet of an enemy creature does not 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 Firearm or Crossbow with the light property you are holding.
