As you skim Bo9S, remember that a nasty AC is really hard to get. King Grommet can occasionally give someone a +9 shield bonus to AC against a single attack, but getting into the 30s is no easy task. With 2 spells Grommet can get up to an AC 38 conceivably, but that is the extreme upper end of the scale for our lvl. And he is a Crusader/Cleric/Ruby Knight Vindicator for the record ;p
