I confirm, Valeska arrived with only 6 archers, but they were with Orrin, who came as the second hero, totaling 21 archers...
111-117 Valk is level 4, received wisdom, Orrin is level 4, receives earth. Near the castle there is an external dwelling of horses, guarded by a crowd of magma firs, decided to take it on the second turn. Took two crypts, mini and one with 5 vamps, spotted the Dragon Utopia, naga bank, and 2 dwarf mines..
121-125 at 121 Valk hits 16 vamps with a grade stack, transfers troops and returns to the horses' external dwelling. Orrin hits 85 spears, 102 gnolls and takes own secondary on 124, but I see that the opponent still has more castles. I set up a chain, transfer artifacts and troops to Valk and with stats 5 8 1 1 she attacks the magma firs. There are 42 of them, bless lasted only 1 round and archers were removing 6 magma firs from the stack and then only 2 remained, as a result throughout the whole battle my troops' morale never jumped, even though Val was an expert, resulting in 7 archers and 13 magma firs remaining, decided not to continue. Thanks for the game..
