Empyreal Sling

An Empyreal Sling is a ranged weapon with the following parts: a stock, a trigger, an ignition system, a lock chamber, and one or more tines. You hold the weapon by the stock. Magical energy is stored in the lock, usually in the form of dracanthracite charges (self-powered), but someone with an Arcane Background can power their own sling (externally-powered). When the trigger is pulled, in a split-second the ignition system uses a small amount of Prana from the lock chamber (or the wielder) to superheat the air in the hollow between the tines to a plasma state. A spring instantly resets the ignition system, and the resulting flip in magical polarity rockets the ball of plasma down the channel created by the tines, hopefully to hit what the wielder was aiming at.
