Walkthroughs for custom maps.

Thanks for the reply, I'll keep that in mind! Yes, the author provides a lot of tips in the text, and there's also a file with detailed author's instructions. And the plot there, with its backstory, is long and quite unique (a Chinese legend).
And in which video exactly do people complete the battle with Finneas in "Wayfarer"? Can you provide a link? I already watched Belkin's video after my victory, to see how he did it. Yesterday, I tried to repeat my successful battle: yes, I managed to do it again, and the situation turned out to be the same, with minor differences. And yet, I still don't understand why the enemy did what he did (it's quite unexpected, and that's what helped me defeat him). Maybe I should record a video, just in case I discovered something new in this particular battle? Although, it's possible that it's due to the specific number of my troops, and it wouldn't have worked out the same way at a different time. I needed to eliminate the fabled and spectral creatures (which turned out to be crystal golems in the replay) in the first few rounds, and the berserker did the rest. And in the end, I just had to finish off the remaining azure creatures.

With Sandro on the Wayfarer map, the battle is the EASIEST OF ALL!

In the battle with Sandro, the main thing is not its difficulty. This battle serves to introduce Kilgor into the game, as only he can win it due to the "+2 to speed" specialization. This is the main "trick" of the battle.
