There was no DD and no possibility to build a 5th tower on the map, so the opponent couldn't catch me for a long time. But he caught me with bait :)
Thanks for the game!
The opponent had 2 native secondary dwellings and 2 external dwellings of bears. Since I was inferior to him in power in the battle - I decided to play for a draw, having hat-control from the Dragon Utopia which the opp didn't notice while clearing the underground region. But without air units, I couldn't see the location of his heroes.
Thanks.
