Evocaria are a type of collectible that are scattered all across Kairos in Borderlands 4. Unlike Vault Symbols and Dead Bolts, players will need to finish a minigame first before they can reap an Evocarium's rewards.

Opening an Evocarium is simple: just interact with all three golden orbs that it points to. Unfortunately, some Evocaria can be tricky to open — the Waterstop Evocarium is a good example of this. If you're having trouble reaching the orbs for this one in Borderlands 4, here's a quick guide showing you where you can find all of them.

All Waterstop Evocarium Orb Locations in Borderlands 4

Like all other Evocaria, the one in the Waterstop POI has three golden orbs. You can find two of them on some rooftops near the Evocarium itself. They're quite easy to spot, but the tricky one here is the orb that's underground.

Jump up onto the roofs to reach the first two orbs, and to reach the third one, look for the spot on the image above. It's close to the orb that's on top of a chimney-like structure. In this spot, there is a hidden path near some machinery on the floor. Drop down, then enter the doorway to find the golden orb at the end of the room.

Once you tag the third orb, go back to the Evocarium to claim your reward. You don't have to clear out the Order goons in this area, but they make for good loot and XP nonetheless.

Evocarium Rewards

sdu tokens

Finishing an Evocarium rewards players with SDU Tokens, which they can use to upgrade their backpack, bank, and maximum ammo capacity for each of their weapons. Typically, an Evocarium gives 15 SDU Tokens, making them more than worth the detour.

Apart from SDU Tokens, players will also unlock a voice recording from Nyriad, a Siren who got stuck on Kairos at one point. Admittedly, it's not as cool as getting a shower of loot, but it's there for those who are interested in the evolving lore of the Borderlands series.

By finding all the Evocaria across Kairos, players will unlock the Stranded Sister challenge, and by doing so, they'll get a splash of XP, a bundle of cash, some Eridium, and a unique skin for their weapons.
