Sand Blaster

Sand Blaster is an Engineer at-will attack power for the University of Fluid Dynamics.

Your education has taught you how to spray sand safely. You crafted a sand blaster that deals 1d6 slashing 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 takes no damage.

The damage increases by 1d6 when you reach 5th leveI (2d6), 11th leveI (3d6), and 17th leveI (4d6). Starting at level 11, the area of effect is obscured by the thick cloud of sand until the start of your next turn.

You can safetly overload your fuel tank to intensify the blast. Doing so increases damage by +2d6 per Overload Point up to your Overload Max per turn, and creatures that save still take half damage.
