Aye - words are odd. It's actually based on Auster, which is the south wind personified (Roman name, based on the Greek mythos). I know what you mean though.
Oh, I hadn't thought of the Southwind. Maybe it would be better to base the name off of another wind (either Greek or Roman), so they don't sound austere. Zephyrus is for to kind, and probably far too well known. (Ironically, the Greek name of Auster, Notus (/Notos)
means well know in Latin.) Boreas was closely associated with horses, just like Tali. He is also older and tougher than his brothers though, and seems to lack the puerility of Tali. The youth and stormy nature of Notos/Auster is probably a good choice, but he (like Boreas) seems a little to malevolent in my opinion. The youthful and disheveled Eurus, who brings very dangerous storms but is still considered to have a kind personality, might be a little better though.
I still think that Austerin is too close to austere though. You should loose the "e." Auster is a second declension r stem, like
vir or
magister. The root is Austr-, with the e only present in the masculine nominative singular. The adjective form of the name is
Austrin(us), not Aust
erin(us).
The normal limit on permanent summons isn't used - it's rewritten in the python-reqs to check the number of Pegasus units and Pegasus-rider promotions in total. I may actually have it based on Air3 in the end rather than Channelling3 though...
Ok, just checking. I do worry that a python prereq that has to check all the units might slow the game down. At least it would only run the check for units with Channeling II (or Air III)
I can see an easy way to make it vulnerable to a specific formation Promotion (either 1 or 2), but not to both of them (the PromotionCombat field is for a single entry only).
Yeah, I've been asking Kael to change the schema to allow promotions to have bonuses vs multiple promotions, but he hasn't done so. He said that he thinks it is a good idea and that there have been a couple of times where he wished it worked like that, but that that type of change would take a fair amount of work and that he doesn't want to do it until he really needs to use it for something.
Feel free to change the schema yourself though. This is one of those changes that is pretty important to a few things I have planned for my modmod. I'd really like to have it if I end up borrowing your SDK. You should add it right after you include the latest version of xienwolf's xml modcomp (Although you can go ahead and include UnitStats and FFHBUG first if you want to

)
