I decided to paint up an Exarch for my two 10 man Dire Avenger squads. It's a fairly straightforward scheme that is rather quick to throw together. When I'll get around to finishing the, or even starting, the other 19 models I haven't a clue.
The real challenge for my Dire Avengers was trying to get a clear difference between them and my Guardians. I think I achieved enough of a difference with the greater amount of wraithbone and the red. The red is an older style of Dire Avengers paint scheme. For some reason they decided to go a more black and yellow accent to the blue.
