I just picked up CM after flipping through it in the store, and I must say, I was pleasantly surprised. I had expected it to suck horribly,but it's a decent book overall (IMO).
In any case, in reading through the PrC's offered, I came upon a dillema: The PrC Abjurant Champion gets the ability to add his class level to any armor or shield bonus granted him by an abjuration spell.
The ability, as quoted from the book:
"Abjurant Armor (Su): Any time you cast an abjuration spell that grants you an armor bonus or shield bonus to AC, you can increase the value of the bonus by your abjurant champion class level. Abjurant champions rely on mage armor
, and similar spells instead of actual armor.
Call me an idiot, but Mage Armor is a Conjuration spell, and therefore not an abjuration spell. While I'd love to believe that it would work, I think they conveniently forgot this fact.
Obviously it'd be up to the DM to rule as to whether or not the ability applies but rules as written are pretty clear to me.
What do you think, oh community mine?
