2 Inferno, a bunch of buffs, and on turn 114, I defeat 43 ducks for the Fire Book.
Then, I hide Devils and get +2 to all stats. On turn 117, I head to the Dungeon computer behind the Devils' portal and get double mana, but instead, I find an opponent with a powerful army in a village on a log.
Oil and 2 Armageddons helped me win, although I could have just defeated everything with Devils:D
The opponent surrendered on the next turn.
Thanks for the game!
