I'm trying to go through it manually. :smile35:
If I don't mess up anywhere and don't misclick, I hope to finish this guy within a couple of hours. I found a new spot; it barely costs any mana. Blindness on 1 elemental is not the same as 2 hypnosis on liches.

Even if it was the most masochistic way, and even on the second attempt (the first was ruined on round 1591 after almost 3 hours of play), the final battle is complete! I'll tell you, it was the toughest battle I've ever fought. And I wouldn't want to repeat that.

But, be that as it may, the phrase "As far as I know, no one has completed it yet" is no longer relevant.
P.S. It's a pity I didn't have time to build a ̶z̶i̶k̶k̶u̶r̶a̶t̶ Capitol. :D
