What losses in mana/troops are considered acceptable? It will be difficult to keep the units alive. To do this, you need to play out a sequence of good casts. I found a fairly stable combination of slow + prayer, and that's what I'm playing with. But I also need a shield to appear in the next cast of the genie.

In the first successful attempts, all enchanters and 30 archdevils are preserved.

Did you ever play through the entire game for ознакомительных целей? Or is that the point - if you play through the entire game, even for ознакомительных целей, it will create a sense of completion and reduce motivation for a super-fast attempt?
