It's because the archmage has to burn spell slots for high arcana, while the hierophant gets his class abilities without needing to burn slots. Also, the archmage does have to burn a feat (Skill Focus) to get in.Corwin said:The thing I didn't get when I read through the DMG PrCs is that Hierophant is almost identical to Archmage, yet the Archmage PrC gets the caster level increases while this class does not.
Still, I think you could actually run the archmage like the hierophant and make the high arcana cost spell progression rather than spell slots. YMMV...
