This mod does NOT affect enemies' weapons.
The Damage Modifier is absolutely standalone and is set to 0% by default. This mod also works with weapons that you give to your companion.




Installation: 

Install with an Mod Manager. 

The "All-in-One Files" and "DLC Single Files" requires Automatron, Far Habor and Nuka World.

Important:

1. If you have installed mods that change the weapon(s) and have their own ESP or ESL file, most of them require a compatibility patch. You must combine the damage modifier changes in the "Weapon" category with those of the other mods in the same category and copy them into a new file. For this you need FO4Edit. Link at the end of the description.

2. If you have problems with other File(s) that change Parameters or other Things from the original Weapons, set the File(s) in the Load Order past the DMG Modifier File(s)

3. I added "Grognak's Axe" and "Salvaged Assaultron head". The following only applies to the weapons in the 1. All-in-One, 3. Base Game and 4. Automatron file.

The chance that the damage modifier of the two added weapons will work if you have already found them is 50/50. I had to add a "ma_" Keyword. It was not intended by Bethesda that these weapons could be modified in the workbench. The weapons could not update themselves automatically. Just cheat with the console and it works. If the weapons have not yet been found or when starting a new game, the weapons update automatically.





Only affects users of the single Files:

1. Don't combinate single Files with the Base Game Merge File. Single Files can be combinate with DLC Merge Files.
2. Only Merge File includes Melee and Fist Weapons.


Incompatibility and Known Issue:

1. The mod could possibly be incompatible with CC content for the Weapons. I don't use CC, so I can't guarantee it. 
    I will not fix bugs that occur with CC Content.

2. If the Mod "Visual Reload" does not work, place the "Visual Reload" Mod past the "Damage Modifier" Files. 
    It may be necessary to reinstall the mod every time you install a "Damage Modifier" File.



Future Plan:

1. Add Damage Modfier for all Base Game Vanilla Weapons. (as single File)  Complete
2. Add Damage Modifier for Automatron Vanilla Weapons as a Merge File. (only 3 Base Weapons)  Complete
3. Add Damage Modfier for all Far Habor Vanilla Weapons as a Merge File (only 5 Base Weapons)  Complete
4. Add Damage Modfier for all Nuka World Vanilla Weapons as a Merge File (only 4 Base Weapons)  Complete
5. Create a Merge File for Base Game Weapons.   Complete
6. On demand "All-in-one" File and "Lore friendly AIO" File added.   Complete
