[Immaculate]

While i agree that bee-lining enchantment is a strong opening for Sauromatia, another option, should you not wish to invest in 'enchantment 3' right off the bat (maybe you want to go evocation first or construction first) is a quick hop over to conjuration before anything else. Instead of going 3 layers deep into enchantment, go 1 layer deep into conjuration then go for whatever you would normally go for.

Why conjuration first:

1) Tangle vines: yes, they aren't GREAT... but what they do, they do adequately for what you need. Every warrior sorceress can cast this (instead of bringing a witch king to cast death-based enchantment spells) and its available earlier. What it does is tie up those heavy cavalry and elephants that make attacking independents troublesome. Lots of androphag archers and some tangle vines (and maybe a few amazon spearwomen to protect your archers/casters) makes a pretty competent expansion party. The advantage is availability. This comes much earlier then enchantment three.

2) Death/Nature Warrior Sorceress cast summon ancestor. Again, not a GREAT spell, but it does what you need it to do... suck up enemy movement while your archers pound on the enemy. Sure they only have 1hp but they have ethreality and because they are charging out beyond your caster/archer ranks, the enemy will converge on them, try to pound on them (usually successfully so within a turn or two) and finally kill them. During that time you've hit the indies with another round of arrows and you've summoned another ancestor. The indies will still charge at you but hopefully that heavy cavalry has used up its lance attack and you've bought more time to fire on them. And thats what its about isn't it?

3) Black Servant. Summon a black servant as soon as you hit conjuration 1, make him into your prophet and use those corpses that accumulating from patrolling your capital (with taxes jacked up >140%) to summon longdead horseman. One important thing about longdead horsemen is that they are immune to hydra poison. Think about that and about the first year of expansion and you can see how those indies that aren't suitable to fighting with archers can still be conquered with tools that you can get rolling with very quickly.

Anyway, while i fully recognize that enchantment 3 is a VERY awesome opening and very impressive, it does take a bit to get rolling with and does require the use of witch kings (which cost more and research much more effectively then do warrior sorceress)

So consider the conjuration 1 path next time... maybe...?
