Electrolyte Fogger

Electrolyte Fogger is an Engineer at-will attack power for the University of Fluid Dynamics.

Your education has taught you how to spray flaming oils and other liquids safely. You crafted a fogger that deals 1d6 lightning damage in a cone. It can be used at-will as an action. You can easily change the shape setting of the area of effect as a bonus action to a 15 foot cone or 10 foot cone. A creature that makes a successful Dexterity save versus your Invention save DC +1 takes no damage.

The damage increases by 1d6 when you reach 5th leveI (1d12), 11th leveI (1d12+1d6), and 17th leveI (2d12). Starting at 11th level, the Save DC bonus increases from +1 to +2.

You can safetly overload your fuel tank to intensify the blast. Doing so increases damage by +1d12 per Overload Point up to your Overload Max per turn, and creatures that save still take half damage.
