Apparently corpses in provinces lets you animate humanoid manikins, which are better than the animal critter ones.
Hnn... not really. Humanoid manikins are like your third worst manikin, after harpies and plain... wolves, or something like that. Both of your best manikins (bear, elephant) are animals, as are... well, all of your better ones but maybe the minotaurs, if you assume the centaurs are naturally omitted. The order of quality goes something like harpy->wolf carrion beast->plain manikin (humanoid)->boar carrion beast->satyr manikin (humanoid)->horse carrion beast->mandragora (humanoid?)->minotaur manikin (humanoid?)->bear carrion beast-> elephant carrion beast. And of the upper ranks, the mandragoras in particular are quite rare. You can do a
lot worse than an aspho chaff blob made mostly from the better carrion beasts. The humanoid ones
do tend to have somewhat better attack/defense scores, but it's fairly marginal and the animal one's greater HP/protection tends to (readily, if you've got access to H4 via prophet or booster) make up any difference on that front.
As for the water bless, I generally... well, personally, I don't really see the
point to taking a water bless if you're not going major. Defense isn't a particularly sexy, well, defense stat. If I were going for an expanding pretender, I'd probably nab the gorgon or great white bull -- s'like I said, regardless of anything else you want at
least that minor earth bless. Any nation with as many sacred casters as aspho has wants that minor earth bless, heh. Still, if you
were going with that dragon, with the intent to bless your black centaurs, you'd probably want to go ahead and get W6 and completely offset the berserk penalty, heh. Though... do remember, if you can nab up at least S1 indies, which isn't
terribly unlikely, you can start putting out shrouds for your pans. Good stuff, that, if you've got N/e.
As for the extreme temperatures... well, there's something to be said for that. I'd still almost want to go for heat instead of cold, strictly to deny
enemy undead that extra boost (and make using your own in conjunction with your unresistant chaff horde less painful), but particularly if you take the currently incessantly hammered upon minor earth bless, it wouldn't be that terrible for your more prolific battlecasters, as well. I guess it depends mostly on what other nations are in the game with you -- if you can handle going extreme either way, might as well pick the one that's going to cause the most annoyance for the most people.
Incidentally, your main battlefield casters are probably going to be living dryads (hag or otherwise) and panic apostles -- carrion lords and ladies are honestly too expensive to use en masse, so you'll be leaning on your recruitables for on-the-ground force projection. The carrion ladies are actually kinda' total junk (better two centaurs than one lady, >95% of the time) and I would probably never recommend summoning them, honestly, whereas the lords are SC-chassis and heavy battlecasters/mass manikin buffers -- specialists, instead of something you're going to have tons of. And your other casters are all recruit-
anywhere, which means if you can mumble up the gold you can have an unholy bucketload of them, especially if you're not spending (much) money on supporting actual troops.
As for the F/E divergence, remember if you can get fire brands (which would be nice strictly to give you diversity, and make it so the enemy can't just casually slip on cold res and ignore your thugs) you can probably manage charcoal and gleaming gold shields as well, and both of those are somewhat deliciously brutal. It's nice to have the option, makes you somewhat harder to counter.
... also I'm totally kinda' rambly, so anyone with better ways of putting any of that are terribly welcome to join in. Ruddy painkillers.
