I just realized this due to a play session in which one character was going to die and another had a limb cut off, and it doesn't really seem to make much sense to me. I hope I'm doing things right.
The thing that seems weird to me is the difference in what you have to do to preserve a body vs. what you have to do to preserve a limb. In a way, it seems it is EASIER to preserve a whole body than it is a severed limb.
Let's say you get your limb cut off. You look on the closed channeling lists, and see the spell 'Limb Preservation' on several lists as a 5th level spell. Each spell specifies that to preserve the limb, even if it is severed, you need to cast the other three 'Limb Preservation' spells on the other lists (the lists are Bone, Muscle, Nerve and Blood Law).
Now let's say you want to preserve, not just a limb, but an entire dead body. Surely, this will involve a lot more power point expenditure, no? Actually, no. All you need to cast to preserve an entire dead body is a single Preservation spell from the Cleric list Life Mastery, a level 7 spell.
So, to preserve a single limb is 20 pp and four spells; to preserve an entire body, 7pp and one spell.
Doesn't this seem a bit out of whack? My player was asking, 'can't I just preserve the whole body?' I didn't really know what to say.
Am I doing something incorrectly?
