The game randomly assigned us the same Castle. The second hero was Tant, and no more Necromancer heroes appeared. I had to level up a Mage. There was only one road leading to the Necromancer's Castle. Three weak peasants were sent along the off-road path. In the end, on day 121, I captured the Necromancer's Castle and recruited three Conscripts - a level 2, a level 2-4, and a level 3-4. With reinforcements on day 122, I attacked with the level 2-4 - the auto-battle predicted a loss, but it turned out to be a close fight. The level 3 unit, with 300 skeletons, and Tant with stats of 2, 0, and the last speed skill without magic (he only had enough mana for one Animate Dead spell), barely managed to win, losing over a hundred skeletons. He then leveled up Earth Magic from 0, and on the next turn, with a Scroll of Haste, he took another level 3 unit. On day 124, the weak hero took a level 2 unit - a total of 8 Angels. There were no artifacts in sight, so I took a couple more Hive units and prepared to flee with Tant to the Treasure Castle, but I encountered a couple of blue weak heroes and ran off-road towards them. Then I took a village, sent Tant there, found a Teleportation Scroll, and built 4 Guard Towers in the same day (there was an Armageddon and a Teleportation spell). I defeated a Utopian, and on day 132, I took a level 3 unit, losing an Angel - I received a Shield +12-3, a Crown of Wisdom, and a couple of bags of gold. The opponent's main hero was heading towards my village, and I used the Teleportation spell to attack him on his own turn.
Thanks for the game!
