but if they VERY RECENTLY died, you should be able to just use like a heal spell or something and it should save them.....in real life cpr can bring someone back and we dont even have magic
CPR only works in certain situations. How often does CPR revive someone who was beaten to a pulp by an Ogre, or stabbed through the heart with a sword? I think if a resurrection spell existed, it would be well documented and mentioned before now.
I'm not saying there can't or shouldn't be one, so long as it's acknowledged as a new thing, or discovered by the player his/herself.
