Discussion about Heroes I.

I already asked, but I'll ask again. Is there a way to quickly find out which spells are in the Tower, with level 4 being required, of course.
Or is the only way to collect 20 of each resource. But for that, I might have to play for 10 days, and there's no market. It won't be scouting, but rather a rough pass. Maybe there's a cheat program - I look at the initial save once and that's it. I understand that I'm only interested in 1 spell.
Essentially, this is the only thing that can change the strategy on this map.
