Wulfsten's Challenge - "Laslo" [Campaign 2, Mission 5]

Here's how I played through the entire campaign: I leveled up the Arbalest for Wulstren on Laslo's mission, earning a bonus of 10,000 gold, and quickly built up a dragon army with Duncan. I dug up the Tear in 4 weeks, amassed a large army, and went into battle with Laslo. It was a very difficult fight; I killed everyone except the dragons. I survived only thanks to Armageddon and the ability to teleport.
