Flamethrower

Flamethrower 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 flame thrower that deals 1d6 fire damage in a cone or line. 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, 10 foot cone, or 20 foot line. 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). The target also becomes frightened starting at 11th level.

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.
