ZTG -1 DAMAGE ISSUE

There is no info that says it will only take 1 damage if it has an armor plate.

Not begining of the fight. After %80 start to take only 1 damage if there are armor plate. So with rampage damage and speed they deal so much damage and take turn after turn. This is absurt. How am i get pass this **bleep** lv 70?

The armor plating trigger at every attack and never go down, so always 1 damage if below 3 characters
