Discussion of the Academy faction (Mages and Wizards). Tactics and their specific features.

In my opinion, a mage should primarily focus on upgrading the Summoning skill... and there's a higher chance of finding spells related to that magic in the guild. Relying on finding something on the map isn't a good strategy, although you might get lucky. It's best to build the guild as early as possible, ideally up to level 3. But it's unlikely to be beneficial on the hero's skill set. I don't understand why you'd take Darkness. It only seems useful against a Necromancer. Of course, your "Forgetfulness" spell is my favorite, plus Subjugate and Berserk... it's terrifying. Someone seems to want to turn a mage into a Necromancer:D. And you can do a lot with Chaos using the Wizard's Sign. For example, I played a duel with Oraz vs. Ravenna... we put the Wizard's Sign on the vampires or liches and cast Chain Lightning, and it was devastating. If you only have golems and tumblers left, there are no problems with Chain Lightning. For maximum effect, you can also upgrade Luck + Lucky Sorcerer, then it will really be effective. But still, it's better to stick to the standard: Summoning + Light, or just one of them (preferably Summoning).
