ACFs.
Some state exactly that you have to have X to qualify, and some are up in the air. ALL of them are under some sort of listing like Ranger or Monk.
So, if I had a ACF that said (give up level 1 bonus feat) and I had a class that had a level one bonus feat, but the ACF was listed under say, Wizard, or Erudite, or Psion (nomad). However, the actual ENTRY ITSELF didn't say anything about you needed to be have anything from being a Wizard, or manfester level, or specilized in being a nomad.
Ignore the fact that some ACFs would be pointless and useless, What is the RAW?
I certainly know the RAI of the situation. No question. I'm talking TO here. Absolute limit here of how far you can push it.
I'm leaning towards No, simply because it would be a whole lot less work for me, but If I'm going to work out the ultimate guide to stuff, I need to have absolutely EVERY POSSIBLE RAW COMBO. That means even if I don't want something to be a certain way, I have to consider it.
Case in point, the most extreme cases I can find.
Erudite is actually a Variant class of psion.
Being a variant of the original class, you should be able to use

Ever more extreme example:
Psion (egoist)
Change Shape
You gain the minor change shape ability, like that of a changeling.
Level: 1st.
Replaces: The bonus feat at 1st level.
Benefit: You gain the minor change shape ability that is possessed by changelings.
The Bonus Feat says only The Bonus Feat at 1st level. So a fighter get "bonus feats" at first level.
Can he take it?
The ACF is under the Psion (egoist) entry, but nothing specifically says it HAS to be only Psions.
Does it say that it does SOMEWHERE?
Save me the need to redo EVERYTHING I've been working on.
