Pact of the Gunslinger

In some worlds the knowledge of firearms was deemed too dangerous for mortals to possess. As such, the great powers across the planes gathered all such knowledge and sealed it away to protect it from abuse. Recently some of this knowledge has been leaked to lesser beings, such as the devil Neratusa and the Mind-Under-the-Mountain among others, such entities have in turn begun to share it with mortals... for a price, of course. 

The great powers have since divided into factions, bickering amongst themselves. So long as these lesser beings only share the completed objects to a chosen few, while maintaining the knowledge of their construction secret from mortals, they are permitted to continue. As many of the great powers privately hope these god-killing weapons to turn on their enemies.

Mortals who make a deal for access to these weapons become warlocks bound to one of the many patrons by the Pact of the Gunslinger.

Forbidden Designs

At 1st level your patron grants you one type of firearm. You are proficient in the use of these weapons and use your Charisma for attacks and damage rolls. If your firearm is lost or damaged you may perform a 1 hour ceremony to return/repair it. You are gifted additional firearms at 6th and 10th level. Some weapons are only available a higher levels.

These firearms count as ranged weapon attacks and cannot be used for dual-wielding unless otherwise stated. Bludgeoning/piercing damage from these weapons is not considered magical.

In addition, re-summoning your firearms using your Pact Weapon feature does not repair them if they are broken.
