I'm trying to remember the differences between how the teleportation and plane shift spells worked in previous (pre-3rd) edition versions. It's been a while. (If this is the wrong forum, please let me know which is the right one for this sort of discussion).
I know that 3E messed with the cosmology by sticking the astral plane everywhere, and then made everything with the [teleportation] descriptor astral-dependent. Well, like the 3E Planescape Campaign Setting, I don't hold with that change.
The problem is, I'm trying to figure out the easiest way to make a ruling about how different spells work, and I need to know how it worked pre-3E to do that.
Specifically, did teleport work on planes without astral connections? (Ethereal, Inner)
Where did plane shift work or not work?
If teleport had no connection to the astral plane--not even by indirect coincidence--in previous versions, I'd probably just say that spells with the teleportation descriptor don't require access to the astral plane.
If, on the other hand, teleport didn't work on the Inner Planes, but plane shift did, then I might consider just removing the teleportation descriptor from spells that don't require astral connections.
If neither of them worked on the Inner Planes before...well then we just use the re-claimed cosmology and make travel to the Inner Planes a bit more challenging.
Summoning spells are also something to know about.
I'd appreciate any help from knowledgeable folks. Thanks!
Lemee see....
Well, in the Planescape Campaign Setting book, the Astral dependent spells are the dead-raising spells, the spells with 'astral' in the name, plus divination, duo-dimension, find familiar, identify, and speak with dead.
Ethereal-dependent spells basically encompass the entire Shadow subschool, spells with "ethereal" in the name, any spell that summons an elemental-type creature, energy drain, estate transference, Khazid's procurement, Leomund's Secret Chest, major & minor creation, negative plane protection, reflecting pool, restoration, and vanish.
There are also a few spells that can be astral or ethereal.
I don't recall how blink is described in the PHB, but in the Planescape setting, it's not considered Astral or Ethereal.
