Unlike the other Cauldrons, XI appears to have been rendered unusable due to a natural cave-in. Eclipse cultists have discovered the area and built extensive structures and fortifications in and around the dig site. The central core is still active, and can be overridden. Much of the facility still has power, and what appears to be a recycling center that melts down machine scraps is still functioning.
In order to progress through this Cauldron, the player will have to first do battle with cultists in order to progress deeper. Once Aloy overrides the Cauldron, normal machines will be alerted and will breach the encampment to attack both the Eclipse and Aloy. The player will have to fight both the cultists, and Watchers, Scrappers, Ravagers, and Stalkers in order to escape.
The following datapoints are obtained automatically during this quest and cannot be missed.
Text Datapoints - Machine
- The Cauldron is the only permanent Eclipse outpost outside their Main Base.
- There are two inactive Tallnecks, which appear partially buried by the cave-in. These are the only completely non-functioning examples in the game (the Tallneck in Frostfigures can be reactivated).
- There have been reports when playing on the PC version that Cauldron XI yields Cauldron Zeta's M/Theta Core Log 893V instead of the correct M/XI Core Log 231L. It has been confirmed that completing Cauldron Zeta will yield the correct log.
