Currently your Damage scrolls buff your damage scrolls. Meaning that any time you get 3x damage scrolls from a scriptorium. You have to clear 2 spots in your inventory. Put two of the scrolls there. Then sell the scrolls to get +1 +2 +3 for a total of +6 instead of +3 if you sold them all from the backpack. Probably don't want it working that way, as it's super tedious to deal with.
