Nice Rango reference!

I have to point out a detail that I guess I didn't clarify well enough in the OP- the only moving parts of a cristol is the trigger, and any cristol only holds one crystal at a time; the crystal holds so many charges of a single spell (normally,  put in that), like wands and such in D&D. It would only make sense to carry 2 or 3 spare crystals at least,  twice that for martial types.

You've offered up some good balancing traits,  how do you plan to randomize the effects? Is "backfire" among the risks?

Of course, and others. I was just going to like, set up a wheel or some dice or something with effects on it.

And the Roulette could still work the same even with that knowledge. Random BS go!

Or could go the route of it being a unique and unusually design weapon.
