Hand of Fate. Part 1: On the March

I understand. I just haven't heard anyone call them "Koluny" before. :)
Maybe you could disable the "subordination" ability on the map? It's getting too easy to defeat the main hero...

For the sake of the experiment, I defeated the main hero using practically the same composition, but without using the "subordination" spell. To do this, I had to lure Prokh into Nordford, then I attacked the castle and prevented the enemy troops from reaching mine by blocking the gates until: 1. I reduced the number of enemy troops to a level that prevented the AI from effectively using the "frenzy" spell; 2. I cast mass slow, confusion, weakness, and vulnerability on the enemy; 3. I applied vampirism to all my remaining melee units. Result: even fewer losses (not only the zealots survived, but also all the phoenixes). Time: 153 days (although the extra time was spent not so much on replenishing troops, but on luring Prokh into the castle). Difficulty: highest (hero).
