The device spits an orb of energy at a target which explodes on impact. Make a Basic Ranged Arcanite attack against the Reflex DC of all targets in a 15-foot diameter burst centered on a square within the spell’s range, dealing 1d8 Arcanite damage on a Hit. You must have line of sight and line of effect to the target point (but not the entire area) to hit with this Device.
You can spend 1 charge of Aether Flux when you use this ability to increase the diameter of the explosion for that shot by +10 feet.
