After completing each cauldron, Aloy once again gains the ability to override different machines throughout the world.
Exploring the cauldrons also counts towards 100% completion of the game.
Here’swhere to find each cauldron location, how to get in and what to expect.
Each rewards you with a good amount of XP, skill points and overrides for several machines.
After you’ve completed TAU, the other cauldrons will become available.
A few Leaplashers once again patrol the surrounding area.
There, a few watchers will bury their way out of the ground and attack you.
Defeat them, then go deeper into the gorge until you enter a cave.
Simply keep going down the cave until you find IOTA’s real entrance.
When you approach, a Snapmaw and a Shellsnapper will be waiting for you.
The entrance to the cauldron lies partially underwater - simply swim up to the door and dive.
