"Might vs. Magic"

Played through the single-player campaign from a save file provided by Roman-Andrei. I acted hastily and didn't think things through much. But still:

On day 133, I was ready to attack with the Grand Order. My main mistake was building the Guild of Mages in the Necropolis castle.

It's possible to win, but the question is, why bother? Immediately after the Grand Order, there are 2 Nyx monks, and who knows what else... and no Meteor spell will help. The correct approach is to focus on building skeletons without attacking the opponent, which, as you can see, worked. And if there had been a little more luck in the treasure chests and I hadn't been too lazy to grab the red potion, the outcome would have been different.
