I scorched the Necromancer with Meteor, found a scroll of antimagic, built a Guildhall 3, and from the high ground, I saw both the main opponent and his path to the treasure. Aislin ran past my Guard Tower, chained her Guard Tower, bought Ivor in the center after the library and well, and attacked. As expected, she didn't have enough mana (6), she had more troops, but the fighter prevailed against the mage, and she had 50 mana left.
Thanks for the game.
