This was probably brought up at some point in the past, but searching a bit didn't turn anything up so I figured I'd ask. In SoD, when Xykon gets turned into a Lich, there's the 7 Million Dollar man parody page. It lists Xykon as being:
Heavy Duty: 16d12
Normal Duty: 12d8
What does this refer to? Are there different versions of lich? 12d8 seems awfully low for something as powerful as a lich.
