The latest event tied to Borderlands 3's month-long 10-year anniversary celebration has begun. Called Eridium Week, the event is aimed at increasing your amount of Eridium as well as the items you can use it for. The event is live across all platforms, so you can jump into it whether you're playing Borderlands 3 on Xbox One, PS4, or PC.

During Eridium Week, there will be adjustments to Eridium drops for all enemies. Additionally, the items you can buy with Eridium will also lower in value, allowing you to buy more than you usually can. All of the changes are listed below.

Borderlands 3 Eridium Week In-Game Changes

• All enemies drop Eridium, not just badasses, anointed, and bosses
• Eridium drops are increased more so than they already are in Mayhem mode
• Moxxi's Eridium slot machine will cost less to play
• Crazy Earl's assortment of Vault Hunter cosmetic skins and special guns will cost less Eridium

Eridium has been an important in-game resource in the Borderlands series for a while now, but its role has fundamentally changed in Borderlands 3. In previous games, you use Eridium to purchase SDU upgrades, which allow you to increase your carrying capacity for your backpack, storage, and weapon ammo. In Borderlands 3, SDU upgrades became tied to cash, transitioning Eridium into an in-game currency for cosmetics and powerful weapons.

In GameSpot's Borderlands 3 review, I wrote, "If you've never been a fan of the franchise, it's unlikely Borderlands 3 does enough things differently to change your mind, as the game best excels at continuing what the series has always done: deliver a humorous tall tale of misfits looting and shooting their way to heroism."
