Feature request: Planar traits

[derf_red]

Hi,
unfortunately, I couldn't find an already existing entry on the topic.

I would like to have an adjustment for planar traits. For Instance, if my characters are in the Abyss, which is strongly chaos- and evil-aligned, they get certain (stacking) penalties on INT, WIS and CHA checks that depend on their respective alignments.
Also magic can be either enhanced or impeded. For instance (in the Abyss) the caster level for spells with the chaotic or evil descriptor receive a +2 bonus, while spells with the lawful or good descriptor require a successful concentration check.

I guess some of theses aspects could be implemented rather easily while others could be more involved (e.g. rather broad or vague description of spell classes). Also, there are quite a lot of planes description scattered over the various pathfinder books, so that a modular system (i.e. drop down menues for the various aspects) would possibly make more sense.
