The long and tedious process was largely due to the fact that on day 132, I decided to attack Tanta in his city, lost 26 (all) ducks, and bought my way out for half a thousand gold pieces. After that, everything wasn't fast, but neither was my opponent particularly active within my field of vision. I received Town Portal only after completely upgrading all possible spells, on the second month. Dimension Door was given in the third iteration, which made further fighting possible: my opponent was already digging for the Grail at the respawn point of the Companion Tower, which was clear from viewing the area. And as soon as I got Dimension Door, I took two Dragon Utopias and went to take the tower and scatter the diggers. In the meantime, one of them also had a scroll of flight, giving me full control. But still, things weren't very obvious until I found two more Dragon Utopias, where they gave good stats, КВ, helmet, wings. All this made the units more mobile, and Tazara’s defense became 51. On his turn, the opponent spent the night in a village nearby and was killed with small losses. Black Ball + Berserk on skeletons did their job: the opponent cast only one spell – teleport in the first round.
Thanks for the game!
