That's what I was waiting for, the criticism, and now let's begin: let's take a look at the girls;). And who is this beauty with a whip (she can be given the "Subjugate" ability), besides, giving her invisibility is not a good idea; it's better for her to shoot, and now the "Faceless One" has invisibility. Also, you can play with defense and HP, but I don't think it's worth making a big difference - this is about the "Faceless One" (and it's not for nothing that he is a puppeteer, so let him have "Subjugate" as one of his abilities).
I agree with the "Beast" suggestion; what can you offer as an alternative to "Unconditional"?
By the way, "Liches" should be made into small creatures to maintain balance: 3 large and 4 small.
It's too much for "Vampires" to have "Stun" on the third level; now, "Knights" - I even came up with a description - "Dark Knights" - death paladins riding tireless horses and spreading plague throughout the world - I'll think about how to develop it further.
I would give "Batmen" "Infection" (or whatever it's called in the original), in general, the ability of "Ghouls." That is, spreading "plague," not casting "plague."

By the way, I had another idea - "Fire Breath" for the "Fire Dragon," and the "Malassa Dragons" should have "Dark Breath" - we take "Acid Breath" and repaint it black, or dark purple, and it would also be possible to give all "Elven Dragons" "Prismatic Breath," and make the difference in something else.
- "Fire Breath" for "Dark Dragons" gives 200% burn damage to secondary targets but can also affect their own units.
- "Acid Breath" for "Light Dragons" (except for "Azure") 100% burn damage to secondary targets (standard), but does not affect their own units.
- "Northern Breath" for "Dwarf Dragons" gives 50% burn damage to secondary targets in a 2x2 square (like the "Cyclops"), but does not affect their own units.

By the way, yes, but will it go through? I don't know the mechanism, but somehow I took away the "Acid Breath" from the "Green Dragon," but it still affected the back rows with its green cloud (that is, the "through" effect was preserved).
