and...?

don't forget, though, you're talking about aspects. they might have to rely on a power boost that the more powerful form would take for granted.
how do the demonomicon articles handle the AC issue? since those are supposed to be the non-aspect stats, that would be more applicable.
High natural armor and some have the unholy aura factored in.
Dagon: 54 (-8 size, +2 Dex, +46 natural, +4 deflection*), touch 8, flat-footed 52
Kostchtchie: 46 (-2 size, +2 Dex, +24 natural, +8 armor, +4 deflection*), touch 14, flat-footed 44
Malcanthet: 50 (+11 Dex, +12 natural, +17 deflection**), touch 38, flat-footed 39
Fraz-Urb'luu: 41 (-2 size, +5 Dex, +23 natural, +5 insight), touch 18, flat-footed 36
Zuggtmoy: 41 (-1 size, +2 Dex, +30 natural), touch 11, flat-footed 30
Baphomet: 39 (-1 size, +4 Dex, +26 natural), touch 13, flat-footed 39
Pazuzu: 46 (+14 Dex, +14 natural, +8 insight), touch 32, flat-footed 32
*From cloak of chaos (Dagon) or unholy aura (big K).
**From profane beauty ability.
Only Fraz and Paz have the insight bonus, and both predated the Fiendish Codices.

hmm, at will, so in other words a standard action? well that's lame-o. if it's more like a free action, that would be a heck of a lot more useful.
Yeah, but they only have to do so once every 2 minutes, and can "reset the clock" anytime before then.
Here's what Dagon's strats and tactics say: "He is never encountered without having already activated a cloak of chaos spell-like ability."
