Guys i don't think that Carrion Crown is the best AP for an all occult party and it's not the lack of a full bab melee character.First of all it's going to be difficult getting through book 1 alive without someone who can channel positive energy.
Secondly i think that this is a bad AP to go with a substitute for the divine caster role (cleric, oracle, healing patron witch), i am saying this because, from what i have heard/read about the AP, the delayed access to "remove/restore" spells that a 6th level spells class (with no early access) brings, coupled with the below WBL feature of this AP means a lot of cursed, diseased etc. adventurers.
Hmm, that's definitely a good point. The Psychic's Faith Discipline* gives them energy-channeling and "free" cure spells, but curing status effects might still be a significant problem.
*Thematically speaking, I really like this specialization but I find it hard to develop a character who's devoted to a specific god and yet doesn't have divine class levels. However, since their power can be interpreted as coming from the faith itself, I stumbled upon a juicy idea: a worshipper of Aroden! And it fits CC because he had such a personal beef with Tar-Baphon.
