Walkthroughs for custom maps.

I'm not claiming that something similar happened in the battle you're interested in, but it's quite possible that Djinns, Scorpikors, or Phantom Dragons' abilities were used there as well.

If you also speedrun within such timeframes, the battle becomes much more difficult than against the aforementioned Pope (subjective opinion). We have more limited resources, spells, and troops. Even if Djinns cast Haste on the Sniper and Curse of Aging on the same Arch, it still needs to happen many, many times for Fear to trigger. Overall, it's something out of the realm of fantasy. I assume that the battle was clearly designed to take place on a specific battlefield and with a different strategy. For example, as an option, we already have all the pieces of the Diplomat by this point. If we didn't spend money on unnecessary things and choose the right troops based on speed, we can outsmart the opponent. But again, that person was playing for speed. And with ransom + visiting the Lake of Luck, it takes a couple of days. However, we have many equally valuable characters, and it's possible that while one is out of the game, it doesn't affect the speed of completion.
