Who has enough powerful magic.

I'm playing as Haven, and I'm developing both light and dark magic. Tell me, is there no point in witchcraft, as it's not needed? The general effects are what matter, and the number of turns they will last determines their usefulness. Berserk is deadly even without witchcraft. But how nice it is to cast Blessing and then Curse! That's how a magical Haven can be, even without magic (5 witchcraft spells are enough).
