Damn, I won't make such a mistake next time =(((
Even if it were necessary to go there, it wouldn't significantly affect the completion time in days. Because the tasks are solved in parallel. Let's say, while the main hero clears everything needed in the Inferno lands, another one breaks through to the northwest. The main thing is to divide the troops correctly. And regarding the anti-magic garrison, think about it. It shouldn't be that the condition for success is not a rapid exploration of the map and the ability to fight even with small forces, skillfully using magic. But simply accumulating resources earlier. Because if magic cannot be used in such a garrison, then only brute force can solve the problem. Any idiot can accumulate resources. When they don't need to buy many heroes, they can solve parallel tasks faster. And read on the Heroes portal - I'm not the only one with this opinion. In everything else, the map is, of course, great.
