I added some low level noncombat vitality regen even in harder difficulties as using food to heal irks me.

########################################### Installation Instructions ##############################################

BEFORE YOU DO ANYTHING ELSE: Make a backup/copy of patch.bundle, it's located inside the same folder The Witcher 3 Wild Hunt\content\patch0\bundles.

1.Extract the files in the mod into Witcher 3\The Witcher 3 Wild Hunt\content\patch0\bundles
2.Make a copy/backup of 'patch.bundle', its located inside the content\patch0\bundles
3.Click on 'reimport.bat', there now will follow 3 selection boxes (one at a time):

1.navigate to \content\patch0\bundles and select -> witcher3.bms -> open
2.navigate to \content\patch0\bundles and select -> patch.bundle -> open
3.navigate to \content\patch0\bundles and select -> Noncombat Health Regen - For Higher Difficulties -> open -> save
(just open the folder and don't select anything in there, just click enter or click the save button)
4. Close the command window by pressing RETURN. You may need to press it twice.

The changes are now applied to the .bundles and ready to play. In theory.

NOT COMPATIBLE with any other mod that modified the same files I used.

1. Restore original backed up copy of patch.bundle, delete all other files in folder.


Just a little tweak. If you like it, try my other mod, Lore Friendly Alchemy. It changes the potion system back to something more like the older games/books. It also renders this mod unnecessary, as it's included...
