Tricky is that when you power is magick - you have to level the spells as soon as possible, but for instance Fireball or Firearrow will be only backup spells (or not used at all) later on, but see how many crystals they consumed... not to mention how many crystals will consume the more expensive spells (geysir )

And buying crystals from 100K, 200K, 300K... is like... well didn't I had 25 M few seconds ago?

What did I miss as Paladin at most? Crystals - How to save them? - Alchemy

So if you plan to make carreer as mage - Alchemy is a must (or you need to calibrate what spell you add to your spellbook also what spell you want to upgrade) so it can easily happen : "Hell, Would I just have this spell on max level!"
