Haven't given thought to Cernd yet.
I did make Mazzy a paladin, the paladin steed exchanged for sword of Celestia (bow). With ranged smite and Hank's bow enchantment she can contribute well to the only quest she is likely to accompany the party on (half the things the party does during the campaign goes against the paladin code, so she would be more of a problem than help in the long run.)
Making her look like a miniature quincy wasn't my intent
Vicky bought off her LA by adventuring while the party was in Irenicus' dungeon. They are going to dump her soon though (her necromantic powers are starting to grate on the party druid more and more) So far she has been a straight "save or suck"cleric.
As for Aerie, the cloistered cleric is supposed to reflect "a cleric who sucks at close combat" more than "a cleric who received special training", though the extra domain sure helps. By the time she is high enough to go loremaster, the party will probably be in Underdark already (I need a prc there simply because I can't pull MT for more than 10 levels.)
EDIT: I see I'm on a new page... still looking for feedback on Aerie built I posted 3 posts ago
