I felt like I was racking up Kamura Points too quickly, so I decided to halve the amount you get from Account items and reduce Subquest Kamura points by one-third. Requires Sunbreak Final Update. Optional version of the Account Items version that changes the Power/Armor Charms and Talons to be ammo items. 

Compatibility: 
Less Kamura Points from Account Items will conflict with other mods that edit the ItemData.user.2 file (file path: natives/STM/data/System/ContentsIDSystem/Item/Normal/ItemData.user.2). 

Less Kamura Points from Subquests will conflict with other mods that edit the FreeMissionData.user.2 file (file path: natives/STM/Quest/MissionData/FreeMissionData.user.2).

Either these mods will overwrite/revert changes of the mod changing the same file as them, or the other mod will do the same to these ones. Changes of one mod will have to manually be added to the other's edited file. Anyone is free to add my changes to their mod file and upload it for compatibility, if they so wish. 

My other mods: 
Decreased Monster Rewards
Increased Argosy Prices and Enhanced Argosy Items
Increased Item Prices (Note: conflicts with the account item portion of this mod; if you want to use this one as well, use the "Halved Kamura Points from Account Items" versions from the files, and don't use this mod [the files will overwrite each other])
Weaker Palico and Palamute Weapons

Permissions: Don't sell it or put it behind a paywall. Otherwise, do as you wish with it.
