Good point. I'm just going to assume they wrote CE on the slaughter wight when it should have been LE. It's funny, I was just wondering what would happen if you advanced a wight and added Lurking Terror to it, then got to thinking about Eviscerator and Death Master because of a wight-like creature from the old Companion set that caused fear... then I noticed the slaughter wight, which is very close to basically that. But it's CE, with no expalnation I can discern.
