The scenario consists of 12 battles that the player must win sequentially. All troops, skills, and artifacts are preset by the map's author and cannot be changed. In addition to the replays, I'll describe how I approached each battle.
Godric. The only fight where we play as regular Freyda with Retribution after any Light spell. There's an interesting battle script here: as soon as we kill 4 enemy stacks, the remaining 3 switch to our side, but enemy Demon stacks appear. The key is not to touch the strong enemy Zealot stack and quickly kill any other 4 stacks. When the Demons appear, we easily kill them with the Zealots and win. After this, all subsequent fights are played as the new Freyda with Helmar's specialization.
Duncan. The main thing here is to put a single Deflect Missile on the Zealots so they shoot at them instead of our archers. Last time I won this fight immediately and easily. In the new version, it took several retries until everything lined up favorably enough to deal with the enemy Paladins while preserving enough troops to finish off the remaining stacks.
Wulfstan. Single Deflect Missile on the Zealots at the start of the battle, Haste and Slow, then the fight is won thanks to Vampirism on several of our stacks. Overall, I played it that way from the start; the successful attempt differed in that the computer seemed to play more foolishly than in the unsuccessful ones.
Tolgar. A lot of reloads in this fight. The main idea, in my opinion, is that you can't drag out the battle and need to force the Dwarves to come out of the castle and attack us. There were unsuccessful attempts where the enemy had too much luck and too many Stuns. Deflect Missile here seems like a waste of time; in the successful attempt, I didn't use it at all. I also encountered a technical issue: the game crashed twice during the Erls' turn, which seems like a bug in the game itself, not the map.
Arantir. Break the catapult, deal main damage with archers, and watch throughout the battle to ensure the cart isn't destroyed. Use mass Deflect Missile; single doesn't help because the Archliches will still attack the archers. I lost an attempt where Earthquake broke the gate. Then I lost another attempt with two holes in the wall because Arantir took control of the Zealots and they killed the archers. In the successful attempt, Earthquake left only one hole in the wall, on a more favorable side, and Arantir didn't cast anything dangerous.
Gotai. I didn't really understand the concept here at all. I just played a few times and somehow got lucky enough to win.
Kujin. Now this fight I really liked; I'd describe the idea as: "Think like a Demon, not like a Knight." We have a real Knight army and summoned Demon stacks. We imagine we're playing as Inferno and take advantage of the fact that the computer ignores "gates" if it can hit a real stack. There were some retries at first, but as soon as I focused on the right tactic, I won immediately without any problems.
Ylaya. It's important to choose the right positioning, otherwise it's a loss. Single Deflect Missile worked poorly for this fight even in the old version; there's no point in even trying it here. So we cast mass Deflect Missile, the computer's target selection logic becomes very strange, and we hope it rarely chooses the archers. The archers deal massive damage here, and after several reloads, the fight is won.
Zehir. This is the very fight I couldn't win last time. Here you need to start with mass Deflect Missile, then force the enemy to attack one stack at a time rather than all at once (I don't know how to explain it better; there's a replay). Also, the random number generator was clearly better this time. Funny enough, this is the only fight in this playthrough that I managed to win on the first try.
Zehir (second battle). An interesting and beautiful fight that required some thought. I eventually came up with this tactic: mass Deflect Missile, then mass Dispel to remove the enemies' Deflect Missile. It's important not to break the Hive or the Wall of Swords so the enemies can't reach us. We shoot the enemies with archers, and when we have a big advantage, we all rush forward and finish them off.
Freyda vs Freyda. The fight consists of three stages: first we fight against humans and undead, then against elves, and finally against humans again. Losses from the previous stage don't carry over to the next, but everything happens within a single battle, meaning if you lose on the second or third stage, you have to play all three again. I quickly figured out how to win the first stage, then managed the second, but lost the third. Then I had this idea: drag out the first stage so that the enemy Freyda spends all her mana and can't "retaliate" in the next two stages. I did that and won the next two stages immediately without any problems. An excellent battle!
Biara. In this battle, I initially thought I needed to kill all the real stacks as quickly as possible. I played that way, but it turned out that even when left with only gates, Biara continues to fight. After that, I just played for the complete destruction of all Demons. In one of the attempts, I managed to win without coming up with anything particularly original; everything just worked out more favorably than in other attempts.
The scenario was completed in 1 game day, "Battles won: 12", "Battles lost: 0" :)
