Not much to change on that character. By not automatically a class skill, does that mean deifnately not, or not without giving something up? If that latter, how about instead of knowledge(arcana). I don't even understand why Favored Souls, a somewhat martially-oriented divine caster, even have k(a) in the first place..
Second, as I have een redoing my spell list, I noticed that the spells in the BOED don't actually require you to be Exalted. The feats do, the PRCs do, but the spells don't. Most non-Sanctified spells have the [Good] descriptor and thus require you to be good, and the only restrictions on Sanctified Spells are that you have to be good. What is your gernal ruling on using those spells in light of this new information (In light of which I have discovered that the Cleric in my RL campaign doesnt have to be worry about living up to Exalted standards anymore).
