I think as he progresses more and more into a demon he'll get to the point where the rules of demons will apply to him more. Eventually when they absolutely have to get rid of the age I think Thaco will give it to Names, complete his transformation, and use his true name (the name he always wanted to name him instead of the Teller given name) to banish him to hell with the axe.
Something just occurred to me... when did Minmax tell the GAP that he traveled with Kin for a while? I don't think that ever came up. Did the conversation happen off-screen? And if Minmax did tell the GAP he adventured with Kin, wouldn't the conversation naturally lead to the fact that Minmax killed the Goblinslayer, and rescued Kin, and loved her? And wouldn't that logically mean the GAP would be much nicer to Minmax?
EDIT: Oh wait, it was when they found the pillars that showed who they loved, wasn't it.
They've only got Minmax and Complains available to fight, everyone else is either down or otherwise occupied. And the structure of the demons makes it hard to tell, but it looks like there are multiple flea demons attacking. And while Minmax and Complains both have OP weapons, with Oblivious and the Tumbleblade, how long can they hold out against the demons? Especially since they hate each other?
I'm guessing they're going to end up in trouble against the flea demons, only to be rescued at the last minute by Fumbles, who during the fight has embraced enough imprints to become a very powerful spellcaster. Of course, knowing Thunt, I'm going to be completely wrong, and someone's about to die.
So that's the pain cloak, right? So Fumbles will be in crazy amounts of pain but basically invulnerable. He's probably the best one to wear that though. I'm sure he can handle the pain better than anyone else.
Not very well done, I have to say. When trying to determine what it was, I even went back to that page where they identify many of the items (one would have thought that all of them, but no), and the only cloak there was the pain cloak. Also, this cloak has a similar color to that of THACO's blindfold and of the wraps/bandages he wears.
