For the second time today, I'm having good luck with barbarians. Two native heroes and a scout right in front of the Castle, although the second level hasn't been built yet. 80 goblins at the start, a group of them with the scout, there's a hidden stash of harpies, but the respawn point is small and there's not much money there. I'm sending the grunt forward because without ranged support, he won't be able to kill anything. We attack the creatures, take a chest for experience, and the grunt gets his third level – advanced artillery. On day 112, we kill a horde of zombies to clear the path to the second level, where a Dungeon is clearly visible. I estimate that the hidden harpies behind the dwarf horde will be taken in the first week, plus the portal in the Dungeon will give +20 harpies in the second week, and after upgrading them, it will be quite good, not overpowered, but a significant force. There's also a path to the opponent behind the markhor horde... I decided not to take a rest and play with the intention of an early attack. I took the Dungeon, its respawn point is also small, and there's not much money. I built a market in the Dungeon and a tavern. On day 114, the grunt destroys a building and takes the hidden harpies. Another market in the second level. The grunt clears the path to the snow map through a teleport, passes the magic amulet to Krag, who runs deep into the respawn point, where he kills +70 goblins for the Pandora's Box. There are exactly 5,000 gold in the Pandora's Box. I didn't manage to take the Snow Castle... the path was bugged. On the first, second, and fourth days, I summoned creatures in the Citadel and in the Dungeon. There's just enough money to buy creatures and upgrade the grunt to the second level. Because of the delay with upgrading the harpies, I decide to rush with the un-upgraded ones. I was very afraid of a battle with the markhor horde (no tactics), but they chickened out and didn't want to fight, so I didn't bother chasing them. On day 123, I took almost an empty Castle from the opponent, where a lone hero was sitting with a level 1 harpy. On day 124, the opponent surrendered.
Thank you for the game.
