Tactics for Dungeon.

Here's another point regarding the "Shakti troll stack's" ability to break through defenses: I was practicing and generated a map underground with lots of interesting hiding spots (including cats and dragons). Having read about using utopias behind Shakti on the first week, I rushed to level 113 to drive away dragons from just 10-19 un-upgraded human knights:rolleyes: (120 trolls, with a configuration buff, and a starting artifact ring for health:cool:). I thought:smile19:, but it turned out to be:smile34: (they split into 2-3 stacks each and simply overwhelmed them with the number of stacks, although in the first 3-4 rounds they tried not to attack the trolls – they were afraid, but in the end only 10 of them fell, and 6 remained). QUESTION:confused: What was done wrong?
