How To Get Eridium in Borderlands 4

By Daniel Hidalgo | 2025-09-18 08:39:28
Eridium is the lifeblood of Borderlands 4's endgame. This coveted purple currency is essential for unlocking premium upgrades, legendary gear, and exclusive cosmetics. While you'll naturally earn some by playing, truly mastering the grind is key to becoming a powerhouse on Kairos. This guide breaks down the most effective and reliable strategies for how to get Eridium quickly and efficiently.
Whether you prefer guaranteed rewards or high-risk, high-repeatability farming, here are the best ways to build your Eridium reserves.

1. Accept Bounty Board Contracts (The Most Reliable Method)


For a steady, predictable stream of Eridium, nothing beats the Bounty Board system scattered across Kairos.
  • How it Works: These boards offer contracts with clear objectives, such as assassinating a specific target, clearing an area of enemies, or retrieving a rare item.
  • Why It's Great: This method is incredibly reliable. The objectives are straightforward, and the Eridium reward is guaranteed upon completion. You can hold multiple contracts at once, allowing you to complete several in a single efficient run.
  • Pro Tip: Always keep your contract slots full. Before returning to a hub area, grab new bounties so you’re always working towards your next Eridium payout passively.

2. Actively Pursue In-Game Challenges


Borderlands 4 is packed with a near-endless list of challenges that track your every action, from specific enemy kills to mastering weapon types.
  • How it Works: These challenges are tiered. As you progress through each tier (e.g., "Kill 10, 50, 100 Skags"), the rewards become more substantial, often culminating in a bonus of 25+ Eridium for the final tier.
  • Why It's Great: Challenges provide a fantastic passive income. You'll be completing them naturally as you play, but focusing on specific ones can significantly accelerate your Eridium earnings.
  • Pro Tip: Check your challenge log regularly. If you're close to completing a high-tier challenge, spend a few minutes finishing it off for a quick and easy Eridium injection.

3. Progress Through the Main Story and Side Quests


While slower than dedicated farming, playing through the game's narrativecontent is a foundational way to build your initial Eridium stockpile.


  • How it Works: Both main story missions and substantial side quests often rewardEridium upon completion. The more difficult the quest, the larger thepotential reward.
  • Why It's Great: It provides a large chunk of currency while you experience the game'scontent. You're being rewarded for simply playing the game the way itwas intended.
  • Pro Tip: Don't skip side quests! Many offer unique rewards and sizable Eridiumpayments that will help you afford upgrades long before you reach theendgame.

4. Farm Bosses in High-Value Locations


For players seeking the highest potential yield, targeted boss farming isthe answer. This method trades reliability for the chance at massivepayouts.


  • How it Works: Specific endgame activities and locations are known for bosses andmini-bosses that have a high chance to drop large quantities of Eridium. Focus on areas like:

    • Ripper Drill Sites
    • Auger Mines
    • Order Bunks
  • Why It's Great: This is the best method for earning large amounts of Eridium in asingle run. Defeating a boss can often net you more currency thanseveral bounty contracts combined.
  • Pro Tip: Increase the difficulty. Playing on Mayhem Mode or equivalent higher difficulties dramaticallyincreases the number of resources dropped from enemies and bosses,making your farm much more efficient. Pair this with Luck-boosting gearto maximize your results.


By combining these strategies—using bounties for steady income, challenges for passive gains, and boss farming for big scores—you'll never findyourself short on the Eridium needed to dominate the endgame ofBorderlands 4.
