"Escape to Salvation" - "Magnificent Retreat" [Campaign 4, Mission 4]

valleriv, Zehir's army isn't that significant, except for the Titans. I bought them using his abilities. At the end of the mission, 4 decent stacks of level 7 units join you. If you don't take them right away, their numbers will increase by about 10% per week. In the final battle, I had 420 joined units and about 100 of my own – Biar was defeated.

Most likely, I'll have to replay the last mission as Wolfsten and leave him with a set of dwarven artifacts.
