Bosses

Hello everyone, could you please tell me if there is a mod that adds bosses to the map editor, similar to those in Heroes of Might and Magic VI or King's Bounty? If such a mod doesn't exist, can I edit a unit myself in the editor?

To accommodate a large number of new creatures, including bosses, you need the NCF mod.
There should be another tutorial on creating NCF creatures somewhere, but I can't find it right now.
Otherwise, if you want to create a boss, make a regular creature, give it more stats and level 8, and that's it.
