Solid Light Emitter
How would one go about creating an artifact similar to the "solid light emitter" used by Crimson Tellach (pg.45) and pictured in the Ninth World Hub banner? It seems extraordinarily useful, sounding like the Numenera equivalent of a sonic screwdriver.
Solid Light Emitter: It's described as a "solid light emitter that allows her to create a temporary hand, weapon, tool, or anything else she needs."
How would it operate (depletions, limitations, etc.) and what crafting skills would likely be required to make it? (Thinking in terms of a potential Crafts Unique Objects player.)
