Eridian Focusing Stone

"“Tannis believes this Relic has been passed down through the Eridian timeline to manifest rare currencies to those who consume it's knowledge. Perhaps doing so will result in something rather special?”" Eridian Focusing Stones are a new item added in the Omega update for Borderlands 3 Redux. They serve as an exclusive reward within the Guardian Takedown, and are a Non-Instanced item. The Stones can be obtained via defeating Scourge the Invincible Martyr at the end of the Takedown.

When a Focusing Stone drops at the end of the Takedown, players will encounter it much like any other item in the game. Going over to the Stone and picking it up will instantly make it vanish and convert into 1 Diamond Key which is then awarded to the player's inventory.
