The 4th annual offline tournament, "Best of the best".

But what is the absolute minimum time possible to complete the map?

If I manage to break through the anti-magic garrison in the beginning of the 2nd week on day 121, I think I can complete it in about 16 days... Otherwise, it will take at least 20 days. I don't have time right now, but when I do, I think I'll adjust my plan - I'll attack the necromancer one day later, i.e., not on day 116, but on day 117, but I'll save on buying heroes (i.e., buy fewer of them) and buy more creatures. Then, starting from day 121, with all the Necropolis creatures, I'll rush to break through the anti-magic garrison. If 7 stacks of units are not enough, I will try to attack with another hero first, weaken the anti-magic garrison as much as possible, and then attack with the main hero and the necromancer troops. The situation is complicated by the fact that before the battle in the garrison, you need to defeat 90 efreets, and you can't save between battles, which means you need to defeat the efreets with a non-main hero. It's just unclear why, when you attack a garrison, the battle first takes place not inside it, but with the efreets that are standing BEHIND the garrison, i.e., further away.
