I got lucky — in the tavern, the second hero turned out to be Galthran with two stacks. The middle roads were dealt from a Dungeon start. On 115, I maxed Necromancy for Clavius and Galthran, broke through to the center, picked up several stat boosters for Galthran, and freed Christian at level 5 with a ballista from a prison. The plan was to build cavalry in the Citadel, kill the AI in week 1, and necro-stack. On 115, the opponent surrenders. Thanks for the game!
