What about giving me the GM credits that doghead dropped? I never expected to get the normal XP (though it would be nice), but I'm feeling pretty bummed because I (incorrectly) expected to at least get those GM credits. This is a pretty unusual circumstance, I think--it wasn't like I made an adventure and brought along Zaeryl as an NPC.
I'm not sure where you got the idea that Zaeryl is not subject to losing XP or items? I've already killed Zaeryl's horse, actually--I'm not sure if he's going to survive. If he dies, I guess none of this matters anyway.
