Quote from: Endless_HelixMaybe there are a couple different types of charge, and each charge can only fire specific kinds of bullets. For instance Dragon's blood, congealed and powdered will fire gold and gem bullets, a Caul from a demon might only fire human bone fragments, and Basilisk venom and Phoenix tears mixed will only blast away living tissue.
That's actually what I was thinking of doing using the different types of fulgurite. A little elemental power to a gun. Maybe even necromantic power if the fulgurite was created in an unhallowed location.
