Just about to start running the adventure after running my group of new players through Rusthenge. Really love the book and the setting, and the freeform approach to the Pit.
I was wondering though, the book's pretty explicit on the Sandpoint Devil being able to return, but says nothing about Ripnugget. Surely, at the level they should be at when they defeat him, they won't have the resources to disintergrate the armour, leaving the option open for his return? What should I do about this? Is it fine for him to be a returning threat? The sidebar for the First Doom implies he completely survives the encounter with the PCs, but it seemed a little harsh for him to blow up Sandpoint through sheer immortality!
I imagine the rest of the Whistlefangs will head off after his death, but I don't know whether it's fair to have him returning of his own accord, especially since it's (on average) less than a week before he regenerates. Any advice, those who've run it?
