Gunner (Revised for Critical Role firearms rules)

You have spent enough time around firearms to know more than just the basics. As such, you gain the following benefits:

• Increase your Dexterity score by 1, to a maximum of 20
• You gain proficiency with Firearms (see "Firearms" from the Critical Role homebrew rules)
• Decrease the misfire score of firearms you are proficient in by 1
• Being within 5 feet of a hostile creature doesn't impose disadvantage on your ranged attack rolls
