Wasted crystals...

[Infiltrator]

Hi guys, this is my first time playing, and I've came to a realization I might have wasted a lot of crystals on stupid spells. I kept hoarding them and then, without looking at them, spent them on leveling up crappy restoration spells (heck, I even wasted them on some destruction spells I hardly use).

I'm in the Eastern Isles and to be honest there is quite a shortage of the little buggers now.. any suggestions? Get the crystal reduction talent (Alchemy) or something? Or am I about to run into a horde of them again?
