Does anyone have maps that are truly challenging and interesting, not just for beginners?

I remember a challenging map called The Longest Journey... during the game, you have to defeat terrifying heroes like Tazar, who is around level 40, with about 80 defense and 1000 hit points, and he's always protected by an anti-magic garrison. In the end, I had 92,000 skeletons, and I didn't defeat the enemy hero on my first try, but I succeeded on the second. I recommend playing it on 200% difficulty.
