more fractory-posting but in my replay of it i have finally unlocked Resonance
basically what resonance does is, it puts a stat called "flux" on immediately downstream crystals, and when the flux on an immediately downstream crystal equals the total of the resonant crystal's immediately upstream crystal's base stats, the flux is converted to those base stats. basically it lets you clone a crystal exactly as many times as you want, massively simplifying mass production of crystals
