I love magic. I love burning people. Recently, I also learnt how to bring them back to life.
I'm using the Raise Undead spell to raise enemies I've killed already, not mainly to aid me in battle, but just so I can kill them again. This provides a lot of experience in spell-casting.
However, after I've killed them again, they are reduced to an ash pile that cannot be reanimated.
Is there any kind of spell or another way to kill someone more than twice?
