Storage Deck Upgrades. I didn't have the term in my head when I wrote it and had trouble trying to describe something which increases the amount of ammo you can carry for each weapon type. I'm hoping there is an achievement for maxing out all the upgrades like there was in Borderlands 2. Then I'll use the Moonstones for other things like making weapons or opening special moonstone weapon chests scattered throughout the game. . . oh yea, and also temporary boost drinks available in Moxxi's bar.
