Inventions

Inventions are limited-use mechanical or alchemical items that an Engineer can craft to mimic supernatural or magical effects, though they are completely mundane and scientific in nature. Once depleted, an invention may not be used until it has been prepared again – however, some inventions may contain multiple doses or may be used multiple times. The save DC of an invention, unless otherwise noted, is equal to 10 + the level of the invention + the engineer’s Intelligence modifier.
