>Do you have any idea of how strong of an army is required to survive an attack from these guys.


A small screen of HI, a handful of priests, one mage casting paralyze. That should handle it with minimal losses.


>Even an army of 15 trolls with 10 archers would still take big losses... especially if they retreat because of the wraith lord.


15 Trolls and 10 Archers?
That's not an army. By the time 9th level spells are in play that's a nuisance raiding force.
