I was thinking of leveling up a bit, equipping myself with potions, and then going straight for the quest key locations. I would have to generate several semi-hidden spots, but large enough to fit 2-3 heroes. After taking the key location in the southwest, I would retreat to the Castle (where I would already have a healer and a combatant), learn some spells, and then continue my green-peaceful activities of killing creatures. At some point, I could also start focusing on Speed. The last two armies would obviously use attrition and graveyard tactics. If this approach worked, it would take about 9-10 days, assuming that in the fourth game, it might be 7-8 days. But if my calculation is wrong (which is very possible, since I'm not very good at the fourth game, and I only had about 2 hours for reconnaissance), and it's not possible to break through like that, then I don't know. I could, of course, try to use the Staff of Illusions to create illusions, but that would take a long time. I think the hideout + healer + combatant strategy would still lead to victory, but I'm not sure how many days it would take.
Although, maybe the developers came up with something very clever?
Well, that's a very good plan for a two-hour reconnaissance:)
I just don't quite understand why you need such large semi-hidden spots
and why you need to put two or three heroes in them.
If you need to split the enemy's forces into several groups, then simple units are enough, and it's easier for one hero to gain experience from a battle than to divide it among three, meaning it's more beneficial for developing a hero to send him alone with units.
Of course, the Staff of Illusions is a great item.
But a well-developed combatant is also worth a lot:)
