So on this topic, ive seen a mod that basically adds a resurrection spell. I would want to require it to ise source so it is a more limited ability. I also think it could add a moral conflict for players. Well cheap out friend died. Do we go kill someone and take their source to save our friend.
Nor so much in my game since source will manually recharge with "long rest." But I think it could be interesting in games with source vampirism.
