• You gain proficiency with firearms.
• You gain proficiency in tinkering to repair your firearms
• Being within 5 feet of a hostile creature doesn’t impose a disadvantage on your ranged attack rolls.
• When you roll to hit, the DM will roll a d20 as well.
  • If the DM rolls a Natural 1, the gun breaks.
  • On a success, this DC increases by one.
  • The DC resets after the gun breaks, or after the PC rolls to maintain the gun during a short rest.
