New era.

I haven't played your Campaigns, but I've watched replays of battles against Udun. I'm curious why you decided to implement this mechanic (changing troop placement) in this particular way. The idea itself is unusual, but as I understand it, it ultimately boils down to finding a favorable arrangement through reloading. Would the balance change significantly if you did this: in a battle with Udun, the tactic cancellation is active (like with Nibros) + some rearrangements are performed on the two lines where the player has positioned their troops? This would move away from standard formations but without introducing such a strong element of randomness (which there already is too much of in this game). It's like Fischer Random Chess in Heroes . But these are just my thoughts. And I also want to say that you have many interesting ideas (I've read comments on the Walkthrough and watched replays), sometimes I even feel like trying to play myself.

I envisioned Udun as a loyal follower of Urgash, inheriting his specialization. Therefore, in this Campaign, Udun and Urgash have similar specializations in terms of implementation. Regarding the specifics, I believe it would be very difficult to come up with a better specialization for a chaos dragon (complete chaos in the enemy ranks).
However, this doesn't make it impossible to beat. I posted a recording of a battle where almost all of my troops were outside the wall and were wiped out, but I still managed to hold out in the battle and resurrect everyone. And I also posted a recording of a battle with Urgash.

Gerter wrote that it is technically possible to implement this differently - by moving creatures instead of recreating them. But this immediately presents several technical problems for me (I don't know how to check if a tile is unoccupied in the combat script, there is no way to use the random function in the combat script, etc.) and the question of whether these changes are worthwhile.
