I need a chart for a game I'm in that shows which planes are which for enhancing/limiting/etc. which schools of magic and how.
There's the one in 2e, but it talks about levels and such, not feats, obviously.
Edit: If none is extant, I could work on one with my DM.
Eyeing Sovelior and Sage's SRD, I see it describes two broad categories of magic in the Inner Planes: enhanced and impeded. You can see the specifics there, but in general, a plane's element is enhanced (spells are cast as if with a metamagic feat, such as Maximize, Empower or Enlarge) and its opposition element is impeded (caster must make a Spellcraft check of DC 20 + spell level or spell fails). A few additional effects occur on specific planes. The Astral Plane subjects all spells to Quicken, and the plane of Shadow has some specific effects on Shadow spells and Light evocations.
I believe no resource presently exists for the magic of the Outer Planes, but I'd be happy to help work on such a project -- the Outer Planes have so much more room for interesting effects available. I've got the 2e sources, presuming that's what people are using as the source material. There's little 3.5 material that I can see in a glance around the Web... planewalker here has one entry on power keys using 3.5 terminology for alignments, but nothing on spell keys or the effects of specific planes.
This would presumably be an important part of the PSCS Chapter 8 release... any editors want to let us know the status of this bit in that project?
