Prerequisite(s):
Build Energy Generators and Capacitors, Gadgeteering. Also note that nearly every Gadget has a science or craft skill requirement that you and your assistant must meet before you can build them.
Benefit:
You can create complex Energy Projection Devices with a Tech Level of Industrial or later. Building an Energy Projection Device takes 1 day for each 500 gp in the price of the Gadget. Building a Gadget uses up raw materials costing half of this total price. See the Gadget building rules for more information.
You can also mend a broken Energy Projection Device if it is one that you could make. Doing so costs half the raw materials and half the time it would take to craft that Gadget in the first place.
Normal:
You can only use craft skills to create Gadgets from the Rennaissance Tech Level or earlier.
