Awakening of Evil

Yeah, that's true. It's a bit boring to have almost all the necessary Dark Magic spells (especially the general slow, general dispel, destructive ray, weakening, and vulnerability) available right from the start of the game.
And that's at the maximum level of Dark Magic.
I've only just started the labyrinth, but I already have all of this.
It's impossible to go any further because on the first map, you simply can't learn spells higher than the third level; the castles only offer spells up to the third level, and there are no spellbooks, and Utopia doesn't give you spells.
