True. I'm still figuring that one out and open to ideas.

I was thinking along the lines of specific properties, but would then have to explain to what ends each crystal does for each device, unless just generalizing it.

Example: Purple crystals operate at a much faster frequency when applied to mechanics or clockwork, perhaps allowing for A.I with faster reaction times and processing power? Which would allow gauntlets to fire rapdily, but with minutely powered attacks, like an energy needle gun.

The idea behind this could be complex, allowing for player created colors and properties from every spectrum of the rainbow, but I feel that might get too complex.

Cryatals will have unique properties and purposes, and not too complex, be assured. I am still working on it.

Thank you for your interest, few more and I will get a rough ooc up and compile a cs template.
