More complicated spell system

[Namel]

Could also make it raise cost if used often. And then when used less price starts going down.

I think if people are forced to use multiple spells then crystal system should be removed. Maybe make crystals increase spellpower or something instead.

And I think scroll limit is really stupid and adds nothing at all for game. Only thing it has ever done to me is force on occasions visit castle to sell scrolls so I can buy one I want.

Just throwing out ideas so that devs can pick best ones.
