Technically, this is the most valuable thing you can buy with Eridium in Borderlands 3 because it’s the only thing you won’t ever replace - unlike weapons. Each of these cosmetic items gives something in Borderlands 3 a fresh new look, and each one costs Eridium. (But don’t worry, there’s a spoiler warning before you get there.) Buy cosmetics from Crazy EarlĬrazy Earl sells a variety of cosmetics that can range anywhere from skins, to special heads for your vault hunter, to decorations for your room aboard Sanctuary. To help give you a good idea of what to do with your Eridium, we’ve put together a list of all the places you can spend it, including the endgame option. While these two may be the only way that the game lets you spend Eridium early on, it’s worth knowing that near the end of the campaign you’ll get another option for what to do with your hard-earned Eridium. The places you can do that are all related to Crazy Earl, the Eridium-obsessed merchant who lives behind a door inside Sanctuary. There are two things you can buy with Eridium: cosmetic items or weapons.
Eridium is Borderlands 3’s rarest currency, but it’s never quite clear where you can spend it or what you can buy.
