Which units would you like to replace/add?

khy) Necromancers shouldn't have anything changed about them) Their zombies are already good starting from level 2, and they shouldn't be made to look beautiful))) These are dead peasants, and they weren't very good-looking in life either)) The only thing you could try is to lower the stats of level 6 Knights, and move the Undead to level 7. Knights at level 7 won't look very good (they should be like Paladins)... but Undead would be perfect there. The main threat is Death)).
