While out exploring the worlds of Borderlands 3, you might have come across purple crystals of Eridium. You won’t be able to break these open right away, but once you can, you can start to buy exclusive cosmetic items from a store aboard Sanctuary. In this Eridium Guide, we’ll lead you through how to break purple Eridium crystals, and where you can spend them.
How to Break and Collect Purple Eridium Crystals
You’ll start running into Eridium Crystals very early on in the game, though you’ll need to wait a while before you can break them. In fact, you'll need to reach the first vault, and take down the giant monster guarding it. You’ll reach this point around 15 hours into the main story. You’ll get an Eridium Gauntlet, that you can use to melee Eridium Crystals so that they can be collected. You do not need to equip the gauntlet, as it will be automatically added to your character’s left hand.
If you’re looking to get a bunch of Eridium relatively quickly, we recommend heading to EDEN-6. Many of the swamps have plenty of Eridium to farm, and you can always loop around in a vehicle to speed things up. The swamps around the Jakobs Manor is a particularly good place to start.
What Can You Spend Eridium On?
The main place you can spend Eridium is at Crazy Earl’s. This is found aboard Sanctuary (with an icon of Earl’s head). There’s a machine outside that sells Epic weapons, and Earl himself will sell you the following:
- Head options
- ECHO Skins
- Weapon Skins
- Room Decorations
Other Ways to Earn Eridium
There are other ways to earn Eridium. You’ll get a ton for defeating anointed enemies. These are generally bosses at the end of missions, and turn into Eridium Crystals when kills. Just head over and melee them to break them open. You'll also earn Eridium for completing challenges in the map menu tab.
