I just came across this Coat-of-Arms on the enemy in a custom battle:
How do I get this Coat-of-Arms?
It's a saltire, and it's only available to NPC factions, because there's no nice way to combine it with a heraldic charge.
Oops, and I just noticed that the forum code needs updating to support the new arms! Will fix this ASAP.
Couldn't you just put the heraldic charge in the middle?
I tried that - the problem is that if I want the charge to be fully backgrounded by the X, I have to make it so fat that it covers nearly all of the coat of arms.
