Rare Stash = 0
Rare Salvage = 64
Rare Vendor = 64
This is actually a very good option for those having issues with the script pausing everytime they sell / salvage. Since you will be stashing all rares with the above config, you can turn off the CurrentInventory check.
No (or extremely low) chance of equipping an item if you dont ID anything, thus your armor should never change.
