- Where can I find a list of what all the announcer calls means? Some of them are obvious ("First blood", "Smiter", etc.) but what about "Apocalypse", "Wrathful" and so on?
These announcements are depending on the number of your kills, i think when you got 10 kills or more he just keeps saying "godlike" on every kill.
- Likewise a list of what all the awards mean would be nice, though I think I’ve finally understood them all.
You get awards for different things, most kills, least deaths, most citadel upgrades bought, most flags captured, really simple if you are the best on a certain thing you get the award at the end of the game.
- Favor and Favor items - how does it work? It seems like you need to earn Favor to unlock the items. You earn Favor in each battle, is that managed by account? What about online play, is it just a matter of playing enough battles so you can unlock it all or what did I miss?
You get favor after every game, 75 favor for winning the game and +15 for each award you get at the end of the game.
The favor points in singleplayer and multiplayer are saved separately, once purchased you can use the item as many times as you want.
- Has anyone made a list of how much War Score is needed for each War Rank?
Not sure about that, I usually just check the "score" ingame to see how high the warrank is, and listen to the announcer.
- The announcer sometimes says, "The Light/Dark Citadel has grown stronger". What does this mean? It seems unrelated to Citadel upgrades and War Rank. Sometime I see new buildings (at least Fortresses) spawn. Is this related to that?
As far as I know it is directly linked to the warrank, for example you get the first upgrade on warrank3 that gives you archer towers on warrank8 you get fortresses, also the health of the citadel increases.
- When does the AI purchase Citadel upgrades? It seems pretty random. Some games they don’t get anything, other games they seem to buy every one of them.
I think it's random, if they got more money they probably purchase more upgrades.
- Are the Citadel upgrades "Blacksmith" and "Armory" any good in the early game?
Not really, I wouldn't recommend getting these ugprades before you got priests.
- Is it possible to see your current Health and Mana pr. second anywhere?
I dont think so.
- Is there a key for taking screenshots in the game or do you have to use external tools?
Not sure. But "print" works in most games for screenshots.
