We also play so that loot drops but nobody gets the XP. Which is weird since at least one of those exploding guys is worth an X, and I can't think of a way you'd ever get to cash in on it.

Regarding the same topic of exploding monsters, I don't have the rules in front of me but I seem to recall someone saying that exploding monsters don't affect unique monsters, but in an earlier thread Rich had said that you could do 2 points of damage to Xykon using an area attack such as fireball that targets both Xykon and an exploding monster. I'll have to check the wording on that again, but I would probably houserule that the exploding damage affects Xykon since he has multiple wounds, however other unique monsters (LG, Redclock, etc) would be immune so that they couldn't be knocked out that easily.
