(FIND 50 HIDDEN ERIDIUM CACHES)
At the end of the 4th Ava murder quest in the 2nd season pass, you get a cool new trinket.
-Most areas seem to have eridium spawns. These are little jars you hit to get a few eridium. They are usually standing by a wall, not in the middle of the open.
- Every map reload, a chunk of these spawn, the rest remain hidden.
- The artifact you got allows you to see the hidden ones. They have a little sparkle on them.
- Achievement requires you to hit 50 of these with the sparkles. not the ones without.
- A good spot I found to farm was the first area of the Jackpot DLC (1). Find the spawns, hit the sparkly ones, reload.
