Necklaces and the Z (did you mean to write that?) Dragon Set are deliberately absent here, or is it just luck?
Just some notes.
P.S. It's best to eliminate the Dark Elf in the first turn (this is possible if you equip all speed-boosting artifacts, but I almost ran out of patience – building up an army isn't my thing, and it's just tedious). Otherwise, he'll halve your army with Chaos magic.
I had to eliminate him with his own army from two castles – but without losing any demons.
P.S. There are no bugs, but there are flaws in the troops guarding various bonuses... some bonuses have no guards at all, or have bonuses with 6 monks in defense, for example. Balance is needed! The garrisons are weak. Developing is really difficult due to the scarcity of resources, as someone wrote above, and all the castles have been reduced in development, as well as the Hero max level of 28. Here, on the map, only rushing is possible, and even that is somewhat difficult. Although, if you choose a long-term strategy, the game might play differently.
P.S. I'm done. In the last battle, ignore the summoned units and focus on eliminating the native troops. I didn't understand what this was about? In the video where Dominion defends itself, it claims that some elf used Light magic???? I played Chaos/Darkness without Subordination (it wasn't available) (Berserk was enough for the final) – it's best to get as much magic resistance as possible, as Dominion plays with debuffs (in secondary quests, it's better to choose debuffs for the enemy than your own buffs), and you should be wary of Shock as a powerful spell.
Here are the first spells that Dominion uses in the screenshots.
Thank you for the game! It's pretty good overall. It will be interesting to replay it with Summoning and Banishment, but artifacts that boost Initiative are a must – Dominion has a very high Initiative.
