I still see witches as ranged units. If invisibility is given to one of the faceless ones, then we won't lose this ability. Let the witches differ, as is often the case, only in their spells, or give one more spells, and the other a whip attack, or some other way to differentiate them between upgrades, considering that one of them will lose invisibility. Then we can skip the "Temptation" skill. As can be seen from the table, the undead will look like this: skeleton, ghost, vampire, lich, death knight, wraith, bone dragon.

Will the ability of upgraded zombies, combined with immunity to slow, balance out the charge attack? Perhaps it's better to forget about the charge attack and give one the "Curse" skill, another the "Weakening Strike," and all of them immunity to slow, for example.
