Help! I'm playing against human players with mages, and my hero is Orac, while theirs is Laslo.

Maxim, what if a player focuses on Dark magic? They won't lose anything; it's available in the guild... they can take the Earth Curse in Dark magic, and there's no Phantom! And everything is fine with the Haven faction.

Well, a player who plays as Humans is unlikely to develop Light magic rather than Dark magic (although they could become a very good Necromancer thanks to the "Fallen Knight" skill), but if they do choose it, they should play as Jaliba, who deflects spells!
P.S.: Why is everything okay with the Haven faction?
