Current questions and answers regarding the map editor.

Is it possible to edit the effect of a hero's basic specializations using the map editor (or even without it)? I simply wanted to "upgrade" the Necromancer Orson's specialization so that, in addition to the usual increase in defense and attack, the zombies would also receive an increase in speed and initiative of +1 for every ten levels of the hero. The only thing I managed to find was the zombie_leader.xdb file in the game's resources, which contains the specialization description files, icon, and name, but there is no indication of the actual effect. I would be grateful for any help.
