Stoned Ape
Savant
For reference/in relation to the debate about OPness/how to handle Unfair, this is my current rough party plan (remember I'm respeccing party members):
MC Natural Attacker Demon
Regill Shield Basher
? Cavalier
Arueshalae ranged DPS of some sort, probably a ranger
Camellia Shaman (no archetype, seems incredibly shit to lose Animal Companion with her base Spirit Hunter thingy)
Ember Stigmatized Witch
Wrath is considerably more difficult than Kingmaker, especially the optional bosses. Certain areas from chapter 3 on really spike difficulty, too.
To me it looks like you're missing a proper cleric for Domain access. I'd suggest turning the Cavalier into a Sanctified Slayer with animal domain so you can then get the Domain Zealot and Additional Domian mythic abilities. I wouldn't want to play without domain access, they are just too useful (Nobility, Community, and Madness especially).
Arue's base class is very good (uses CHA for spellcasting which I never noticed until Desi pointed it out), but if you want to respec her I'd suggest Freebooter (for party buffs) or Rogue 4/Slayer 16 (for debilitating injury, high AB, and good sneak damage).
I think the Shaman class is good alongside a cleric or oracle but I wouldn't want to replace them with one.
