[WraithLord]

Jotunheim:

-> Bless. E10N8, E9N9 or E6N6 if you want a cheaper bless.
-> Skratti rule. With good bless give them the shroud and watch out for low MR - their Achilles heel.
-> Vaettis. Take G3 so that they don't die all over from old age. Very good for various tasks.
-> Gygja thugs.
-> Push strong into blood.
-> Rush. Strong bless advantage diminishes with game progress. Be aggressive early on to utilize it.
As a rule of thumb don't rush strong astral nations. Astral has lot's of counters to small elite armies.
-> cold 3.
-> Communions. Yes, you have both astral and blood and they can be intermixed. Gygja communion masters.
-> Use stealth. You have the Skratti wolf form and all the Vaettis are stealthy. An astral Vaetti can be used to protect from mind hunts.
