On level 112, I managed to complete it on 117 attempts. However, on level 123, the double Guardian of Order from human knights and giants (with an upgrade) without haste and mass slow was difficult to overcome. On level 124, I took Utopia 1, which gave me the Water Book and some other junk. I saw through scouting that red flags were relatively close, so I placed the Grand Mage in the tower – there was haste! Gunnar flew in, killed his units with a wave of death, took the Titan Shield, leveled up mass slow there, and attacked. From there, a chain of units came out, and I had mass haste. In the second round, I used mass slow and tried to reposition. In the end, I emerged with 1 knight and 100+ skeletons.
Thank you for the game.
