A lone planeswalker ?

[gpetruc]

I was wondering what could be the best build for a lone character in a plane-based campaign (starting about lvl 8).
Considering for the "lone" I thought of a human cleric.
Domains (from PHB only): travel (need teleport or when you plane at 400km from your destination it's a hell) and Knowledge (didn't want to go without Knowledge:The Planes)
Feats: Scribe Scroll (always good), Extend Spell (and Persistant at lvl 9), Combat Casting, Craft Wondrous Item (dropped brew potion as it is usually useful for others and not for the caster himself)

My other ideas where:
- wizard (human or gray elf) going for planeswalker (that PrC in the MoP; not sure of the name, as I have the book only in the italian translation)
- psion:nomad

Main problems with arcane/pison where the low hp, low AC, messed up in combat and also planeshift is a 7th level spell )

I'm using 32 point buy, Core Rules + PsiHB + Manual of the Planes + something from FRCS + NetBook of Feats + Mind's Eye (WotC free psionic suff)

Any suggestions ?

What if instead of going alone he would be the member of a "standard" adventuring party ?

In this case probably I would go Wizard and then for planeswalker (No Sorceror because cross-class knowledge: planes is bad because the PrC requires 10 ranks)
Or maybe straight wizard (you can still get in the astral plane with a Dim Door and then seek for a portal there, in case you want to planeshift before 13th level)

I think a cleric is the best you can have. The travel domain is great, but the portal domain (Shaundakul, Eilistrae) is another possibility, and will perhaps be more helpful if you ever go to the city of door. The education feat (from FRCS) may help you cause a lone PC can't rely on other knowledge, and when you deal with the plane and their inhabitant, knowledge (plane, religion, arcana, undead, history...) is a vital skill (this way you don't have to take Knowledge as your domain.)
