The most challenging maps for you.

By the way, everyone says that "Fortress" is a weak faction and that it's impossible to play on the "Impossible" difficulty. But I actually played almost all scenarios on "Impossible" (200%) in Heroes 3 using "Fortress". I like that everything builds quickly there. Then they say that you need to build troops first and only then build resource-generating structures, otherwise you won't be able to play on "Impossible". But I actually build resource-generating structures first and play "Impossible" without any problems. Who is right?
