VHCs are a technology developed by the Artisans. By means of reverse engineering, some replicas have also been made by late scientists. They are able to produce a variety of bullets depending on ammunition. Each has multiple triggers, of course, and many models have personalization options, allowing the user to define which trigger activates which bullet kind.
Plasma bullets - Produced either with an automatic spell, it transmutates the air within the blast chamber into plasma which is then accelerated by a magnetic current. This plasma can burn and shock targets, but may dissipate over longer distances.
Plasma cell bullets - A variant of the previous kind. It requires the gun to be fed membranes, which will be used to encase the plasma, allowing it to travel longer distances, as well as giving the bullets piercing power. The membranes will burst upon impact.
Ice bullets - Cheap solid bullets made by magically freezing environmental vapor, or vapor created by combustion. This kind of ammunition may need time to be produced in dry environments.
Lead bullets - Any common (usually lead) bullet will be able to be shot by a properly sized VHC.
