Thank you. I will change the armor, that's fine. Is there an imbalance? Perhaps, there might be a little... However, when I tested them in battle, it didn't seem that way to me: 25% isn't a very high probability + with the damage I gave them, it can be said that this is the only way to deal significant damage to the enemy. So, compared to, say, the blue arrows from the Sylvan faction, which destroy half of the squad, or even the whole squad, guaranteed, it's not that great. Besides, I increased their cost.
I will fix the descriptions.
