Took 111+112, ended up having to play a bad start. Single Griffin Conservatory, native secondary skill and an external dwelling of shooters - not enough. First time playing as Castle I didn't build any cavalry at all - the sawmill was blocked, then I was constantly short on resources.
Contact happened on week 3, but the opponent decided to avoid fighting for now, Shakhtyor ran deep into the treasure zone. In the end, Valeska with boots and loga quickly captured three enemy castles.
But Shakhtyor takes a Dragon Utopia with only dragons and 4 angels. So he has resurrection, but apparently ran out of mana, since he left without angels. I blocked his exit from the treasure zone, Shakhtyor galloped back in again.
Over the next 3 days, Valka also took a Dragon Utopia, but the stats didn't give anything.
In the end, Shakhtyor, stuffed with artifacts and with 40+ unupgraded dragons, almost reached the swamp castle. I decided I couldn't delay any longer and went for the finale.

Shakhtyor was waiting with the Red Sphere and Shackles, and Valka hadn't learned Tactics. In the end, the dragon stack was shot down, gg!
