A standard caravaneer shotgun, that has been re-designed for a more... intensive use. It has been outfitted with an auto-loading system and a substance adapter.
The different crystals and materials placed in the adapter modify the properties of the projectiles fired. This variation for example uses a Fire Crystal to achieve effects similar to incendiary ammo. Only like, five times more powerful.
Combine that with a simultaneous discharge of both barrels and you have yourself a small pyroclastic flow.
The two barrels are fed by two separate internal magazines, 3 shells each. This permits the usage of two separate types of shells - Slug and Buckshot for example. Also the trigger has been converted to double action to speed up firing speed.
