A Sorceress can cast spells from the opposite school of magic. Not every magical unit can do that.
No, that's not true... many can. For example, the Djinn (from Life) and the Water Elemental (from Death, Haven). Our favorite units :)
But what surprises me most about the expansions is the Goblin Knight. It seems that there is no way to find a weakness to destroy them: neither with magic (resistance to magic), nor with arrows (stone skin), nor with speed (ignores the first strike). All that remains is brute force, which has no strategy. But I always try to take them if I play as Chaos!
This surprises me too... He's like a fully upgraded hero. Also, the Death Knight is very strong with his unlimited terror!
