It’s not any game. It’s Conan Exiles. Sorcery is one of the most relevant content promised during EA by Funcom and delayed on official launching. That’s not an invasion, it’s a core feature. Besides is faithful to Conan lore. A world without magic is not a Conan world.
Nobody are speaking of that kind of sorcery. Funcom has never speaked of lightning bolts, fireballs or something like that. Hexes, buffs, summoning and shapeshifting, and all of that based on corruption levels that decrease your strenght and stamina. Seems a funny, lore friendly and well balanced system. I can’t see any reason not to release it.
