So to explain, I have been playing around with a project of statting out a homebrew Archfey's avatar, and maybe the real thing as well. However, there is a lack of such creatures to compare with in the base rules. You can somewhat infer what an Empyreal Lord or an Archdevil for example is expected to be able to do, and the ballparks they should be in in terms of strength and abilities. But with Archfey, I find myself somewhat at a loss where to start.
And to be specific, it is mostly what you would consider 'universal' features of Archfey. Things such as commonly shared immunities, defenses, common abilities, etc. The specific things for the creature I can handle by myself with a frame of reference. But for the common starting point, I would like to ask what people would think a baseline to build on should look like?
Also, my apologies if this should have been over in Advice rather than Homebrew. After thinking about it for a bit, I figured Homebrew is the more appropriate place.
If you are creating/reworking something for PF1 then this is the forum.
I think you need to outline the creature, its origin/history, abilities, motivation, what plot role it plays, and its symbolism for a story.
While deities don't have ability scores, there are several high tier/mythic avatars. Power really varies.
Ah, my apologies there for confusion. I suppose Eldest would be the proper comparison, now that I think about it? The world the group uses is homebrew but originally stemmed from more DnD 3.5e roots. So the usual Eldest don't exist, and we use Archfey as a term for the type of beings covered both by PF1's Eldest and DnD's more powerful Archfey.
I technically do have two other ones still under consideration and generally hope to do more with the equivalent to the First World. Which adds to my hope to come up with even a small baseline to build into different directions, for example which Great Old Ones (Immortality, Insanity, Mythic rules, particular Mythic abilities, etc.) or Kaiju have. An entire dedicated sub-type for a particular type of creature that share those characteristics, but can then build up and spin their own unique take atop it.
On the face of it for some very basic observations, I would have to imagine Fey that powerful would be immune to Aging and Mind-Affecting effects, for example. And the Fey creature template highlights Cold and Electricity for energy resistances. And high Mythic Rank seems rather given. But it is rather basic all and does not quite scream "FEY!" to me, hence me asking for advice and thoughts on this.
But for some extra asked context, the one I am making immediately is something of a counterpart to one of Lantern King's roles as the patron of the Witchmarket? One cannot go wrong with having strange Fey and other merchants in one place, after all. The idea I have had is that the market is primarily known for trading of strange concepts and in particular words (Power Word X -spells type thing being the simplest thing you can find), but does welcome basically any traders, Fey or not. You can basically find almost anything there, so long as it does not cross the Archfey's rules.
The Archfey goes by "Vendor of Worlds" and only steps in to do trade with those very worlds. So to speak, if you are willing to risk dealing with Fae, there is no better place to purchase a permanent Demiplane, or a world even stranger or esoteric for yourself. If you can pay.
So in this regard, specific abilities unique to the Archfey I can already nail down at being able to innately cast things like Create Greater Demiplane, Permanency, and Gate for basic functionality to let customers access their newly purchased planes. Further, things like Plant Growth and Stone Shape would naturally come with to create finer details within any worlds. I do also figure generally having access to the ability to move between worlds created is necessary.
But the specifics unique to the Vendor I am not too worried about at the moment.
Eldest in Pathfinder are in the same CR/power rang as demon lords, Imperial lords, infernal dukes, archfiends, psychopomp ushers ect, ect. CR 25-30 or there abouts. If you have the Pathfinder Kingmaker 1E conversation Bestiary it has some stats you could try using as a basis. It might give some ideas if nothing else.
