Thundax
Auto-translated
Why read spells on the hydra at the beginning? As I understand it, the Knight attacked, which means there was ballistics involved. We don't approach the hydra; the walls break down quickly, and the griffins and possibly gargoyles fly out on their own, and that's the end for them. 17 units will deal 4-5 damage per shot from the Crossbowmen, which isn't fatal. And when the hydra emerges and the walls are no longer firing, we run away from it and wait for the positive magic to end. Then we cast Blind and attack with all our armies. It would also be good to find 1 gargoyle and add it to your army, placing it in front of the Crossbowmen.
