I failed on day 121 - I didn't buy the spell book, only doubled my mana, ultimately losing at least two days. I took an empty Pandora's Box, checked the Griffin Conservatory - maximum upgrade without Griffins. I ran for the spell book and oil, upgraded 31 Evil Eyes, gathered all the Troglodytes (130) and went in. With Bless and Slow, it went perfectly at the cost of 10 Medusas. Then I rushed to the secondary hero, went to take the Griffin Conservatory there - it turned out to be double.
I attacked the opponent with 6 Angels, Troglodytes, and Evil Eyes, things were worse there, the opponent surrenders upon meeting.
