He had a good position at the top, a stable nearby, and 2 hives at his spawn point. I placed firebirds near his camp, and things started to go my way. On day 127, I took Utopian Max, where I got a Castle bonus for a previously captured town. On day 132, I arrived at his camp with 700 skeletons (9 HP, 70 attack, 5 angels, and 8 birds). Stats were around 20, with full control. I immediately killed Shakti in a rush, and that's how it ended.
Thanks for the game.
