Which hero do you like?

In my opinion, the popularity of the Necromancer stems from a teenage fascination with the "bad boy" archetype. If you look at the facts, the Necromancer is the most useless hero class among spellcasters. Death magic is extremely weak compared to other schools, and a low-level Necromancer is surprisingly ineffective! The only thing that can save him is learning Chaos or Order magic.

Therefore, the best spellcasting class is the Wizard! :)
