I have a bit of confusion about the Raise Dead spell. It states that it can raise a creature from the dead, but cannot do so if major organs needed for life are missing (such as a head).
Killing anyone though will likely severely damage or destroy major organs. Jabbing a sword through someone's heart will leave it in little pieces. Can that heart reform itself if Raise Dead is cast? What if an enemy purposefully grinds it up as best as possible in the chest so nothing is really left except fragments? What if they remove the main heart muscle?
Also, with the head issue - what if someone is beheaded, but the head is held onto the body and the spell is cast? How about if someone is cut in half lengthwise by a nasty trap and then held back together? I'm sure that'd do major organ damage, but if both halves were available?
Some of these particular situations may be arising soon, as you might guess. Best if I know ahead of time what my PCs can fix.
