Several changes.

I want to create my own mod and start with a few changes. First, I would like to make it so that acid breath reduces armor. From what I remember, among the abilities of creatures, only plague zombies can permanently reduce armor. My assumption was this: I would simply duplicate this ability, remove the visual effect, set the attack reduction parameter to 0, and the armor reduction to 4 or 5. I would then give this ability to green and emerald dragons. I found "weakening strike" in the gamemechanics folder, and I was surprised to find that there were no settings for numerical values there. Only visual effects. Does this mean I will have to go into the executable file? Second, I would like to take the "lay on hands" ability from paladins and give it to inquisitors. By default, this ability does not have an icon. If I put it in the spellbook and copy the code lines responsible for adding the icon, will it work?
