Why
- For MAIM's lethal headshots to function correctly, your modded weapons and armor must use the correct vanilla keywords.
- To check if equipment is keyworded correctly, open the MCM, go to MAIM > Misc and enable Show equipped gear on Pip-Boy perks screen, then perform a Force Refresh.
- The easiest method to add keywords is with the EZ Keywords plugin included in the installer. This allows you to attach keywords in-game at a workbench to any items that have a legendary mod slot (most modded items do).
- Alternatively you can add keywords manually with a few clicks in FO4Edit.
When
- Many mod added weapons will already contain the correct keywords (as some are required for weapon perks) so patching may not be required.
- Pistols do not need patching; if none of the other keywords are detected, MAIM treats the weapon as a pistol.
- Standard rifles and shotguns will not need patching 99% of the time.
- Helmets and sniper/armor-piercing rifles are hit and miss, so may need patching.
- Anti-materiel rifles will definitely need patching.
