Ideas and suggestions.

I already suggested an option for diplomacy, so that monster stacks would pass by the hero's army without a battle, possibly for a fee, allowing for a quick advance to the center on Jebus, for example, through diplomacy. Attaching half a stack for money also seems appealing. As for Mysticism, it could be buffed further, for example, to 10-20-30, so that on Expert difficulty, Mysticism would provide enough mana for a daily Direct Damage spell or a town portal.

Regarding the Necropolis, will it be added to other landscapes? It's a very interesting object, and I would like to see it not only on wastelands.
