All right; here goes. Can we confine this one to simply a discussion of the upcoming book and (reasonably specific) suggestions to/input from the authors? Erik and James, you still out there?
I'm going to repost one of mine from the other thread:
me said:
I simply think that it's not possible to generate a single set of archfiend (or deific) stats that'll satisfy everyone, or even a substantial majority, because everyone seems to have their own take on how the archfiends should be done. (F'rex, even though I have access to the Creature Catalog stats, the BoVD/Demonomicon stats, the Dicefreaks stats, and the alternate [powered-down] Dicefreaks stats, I use yet a FIFTH set of stats for the archfiends!) Since a set of stats for the archfiends already has seen official WotC printing in the BoVD (and semi-official printing in the Demonomicon), I'd suggest doing what I think DDG should have done in the first place with gods: Provide a 2-3 page discussion of various philosophies regarding archfiend power levels (should they be gods? Should they be "high-epic" threats? Should they be "low-epic" threats? and why) and a few example stats at various power levels (CR 20-30, CR 35-45, deific) for a sample archfiend or two (my votes are either for completely new ones, or for Asmodeus and Demogorgon, of course!).
Another, judging from the debate on the other thread, might be a short "nature of fiends" discussion that took one of the following tacks:
(1) A full-of-flavor pages-from-a-thaumaturgist's-diary (or balor's diary!) set of excerpts on the nature and habit of fiends. Subjective, compelling, and unreliable enough to be interesting reading and fill DMs with lots of ideas, but not spell out a fiendish ecology in any sort of quasi-scientific or hard-and-fast manner.
(2) A workup along the lines of the BoVD/BoED disscussions on the nature of good and evil, suggesting different possible jumping-off points for a fiendish cosmology. For example, something like this:
"Option 1: Fiends as Extraplanar Natives
In this cosmology (ecology/whatever), fiends (and celestials) are simply beings native to the appropriate plane, similar to the way in which elementals are native to the Elemental Planes, or mortals to the Material Plane. Their alignments are perhaps shaped by the planes on which they live (or the other way around), but they do not have any special connection to mortals. (and so on)."
"Option 2: Fiends as Deceased Spirits
In this cosmological option, fiends are creatures formed from the spirits of dead mortals when those spirits travel to the appropriate plane upon death. They may or may not have mortal memories... (and so on)"
"Option 3: Fiends are creatures who represent Cosmic Concepts
In this option, fiends are living embodiments of cosmic concepts: greed, rage, light... (and so on)"
