How to Farm Eridium by Playing Slot Machines

After completing the Prologue and unlocking Sanctuary, look for the two slot machines at Mad Moxxi’s bar. You can play these slot machines to farm Eridium. The rarity of items you win through slot machines depends on your progress in the game.

It is also more expensive to play the slots later in the game but if you have farmed enough money through different exploits, you can play these slot machines as long as you want to accumulate enough Eridium for the rest of your adventure.

Once you have accumulated enough Eridium, you can go to Borderlands 2’s Black Market dealer and upgrade your Ammo Capacity and Backpack Slots.

It is recommended that you upgrade your backpack slots first as it will allow you to carry more loot. Do note how much Eridium you need for different Black-Market Expansions:

Level 14 Eridium
Level 28 Eridium
Level 312 Eridium
Level 416 Eridium
Level 5 / Max20 Eridium

Furthermore, you can complete “Whaddaya Buyin?” challenge for another 166 Badass Rank by purchasing 20 upgrades using Eridium. For a more help on Badass Tokens, read our Tokens Farming Guide.
