Magic has been discussed, and there will be no real magic ability for players. You can use potions, and items with seemingly magical properties (e.g rings that restore health), but that's as far as it will go. NPCs also have limited "magic". Priests and certain monsters, such as demons, can do seemingly magical things, but what you have already seen is as far as that will go. Think of a superstitious Medieval world, where some of the superstitions are real.
