This is a discussion to share our tips and points of view about the power use of Aerie and the multiclass Cleric Mages. I think that is a really special multiclass and the synergy of the 2 classes, not only of the arcane and divine magic, has some really interesting uses.
So please don't tell that you use her to make undeads explode, or to cast Chaotic Commands on your tank, those are things that every Cleric can do. Same for Time Stop, Improved Alacrity and spamming ADHW, every mage can. Those are true things, but not related to this topic, things like clerical spells in sequencers and contingiences are, as only a C/M can do it.
In this first post I will not give any of my "personal recipes", just point out some of the peculiarities of the C/M.
Using and mixing arcane and divine magic is the first and more self evident one, but there is a lot more.
One is the clerical THACO table. Clerics share the same table of rogues, that caps at 6 (fighters at 0 and mages at 10).
An other is that both Mages ans Clerics have the best castable only on self buffs. The mage has the better protection ones, like Stoneskin, PFMW, SI, Spell Shield, and the Cleric has the better boost ones, like DUHM and Righteous Magic. Only the C/M can benefit of both.
Good THACO, boosted with clerical buffs, in a character protected with mage only ones can make an effective fighter, even if he lack of the APR that a proper fighter have. And C/M has also ways to boost his APR, both cheesy (I think in EE some of them are now nerfed, and not cheesy ones.
Those ingredients can used, from early game to the end, to cook some very tasty recipes, up to AFAIK something like 400dmg x round mlee.
I will post my recipes in the next future, I hope in a short time, but I have some RL problems at this moment so I am not sure when.
Feel free to post your ones, I am really interested as I love to have the whiny one in my parties.
I hope that this discussion can become a good reference in how use effectively the C/M, something that you can link when someone say that Aerie is just a weak, slow leveling, not useful toon.
