Questions about the gameplay of Heroes 6.

Probably, "primordial magic" is equally "useful" for all factions, and the hero deals damage with their attack based on the type of magic they belong to.

Haven - Light, Necropolis - Darkness, Inferno - Fire, Sanctuary - Water, Stronghold - Air. This is also noted in the battle logs ;).

By the way, I wonder, is primordial magic not useful for Orcs? It was quite disappointing that Orcs didn't have it.
