UNIT - Creature Balance + Visual Changes

No, it works on other creatures.

Here, look: I gave this ability to the archers (I even bothered to copy the script part from flybysequence), and the first time it was used in battle, the game crashed, even though these archers only had their standard accurate shot ability, and the target was in the center square. I thought it was just bad luck, I tried again – same thing. Maybe I forgot something? Perhaps I needed to work on the graphical part?

Absolutely, but you can benefit from this bug if you name the ability correctly (enhanced attack or armor penetration) and give it to melee units as well, setting the knockback trigger factor to 0 (disabling knockback).

Interesting. Then you could replace the bash ability of the plate armor units with this ability (even without adjusting the knockback). Because two warriors with the same ability – that’s just not right.

Crystal dragons received a fairly powerful AoE, their native ability "Crystal Breath" + the new "Storm Strike."

Why all this fuss around the dragons? They could have replaced the corrosive breath of the bronze dragons with Storm Strike (which would be canon) with a slight adjustment to the stats – and players would have an interesting dilemma. But as it is, it's just a mess.
