Walkthroughs for custom maps.

Still, an Elleshar without Wisdom and Intelligence, which should supposedly be able to defeat a Mefalu of level 6424 with 10k magma elementals, seems strange.

It can only be defeated with a fire shield or direct damage magic. I had experience fighting specialists in defending against such levels; their creatures cannot be dealt more than 1 unit of damage otherwise. Without Wisdom and Intelligence, it really looks suspicious.
