Horizon Forbidden West Cauldrons make a return from the first game and finding them helps broaden the type of machines you can control.

Horizon Forbidden West lets players override enemy machines and make the machines work for them. Cauldrons are an important part of this, you need to complete these ancient techno dungeons to broaden the kinds of machines you can take over. 

Cauldrons are usually fairly straightforward, but if at any time you find yourself stuck, be sure to activate them as your main quest. Entering a Cauldron doesn’t always do this automatically, so to make life easier it is best to go to your Quests menu, scroll down to Cauldrons and be sure to have the right one set as your active quest.

Cauldron Mu

Cauldron Mu is potentially the earliest Cauldron you will find in Horizon Forbidden West. It is the furthest east of all the Cauldrons, and can be found early in your journey into the Forbidden West. At level 18 it is one of the lowest level dungeons in the game, so be sure to grab it early.

Completing this Cauldron gets you the Burrower, Scrounger and Grazer overrides. It also gives you what you need to craft overrides for the Scrapper, Fanghorn and Widemaw back at the base.

Repair Bay Tau

Tau is a Cauldron that is completed during the story, so no need to go out of your way for it. It will come up early on and is a low-level dungeon, and shouldn’t give you much hassle. This one allows you to override Bristlebacks, which can be mounted. Completing this Cauldron also lets you craft overrides for the Plowhorn and the Grimhorn.

Cauldron Iota

Iota is a Cauldron way up in the most northern part of the map. At level 22 it is the next logical Cauldron to conquer. Iota is an important Cauldron, not only because it gives you several overrides as Cauldrons do, but also because one of the Tallnecks is in there. For more on that, check out Horizon Forbidden West Tallnecks.

Completing this dungeon nets you overrides for the Leaplasher, Glinthawk, Lancehorn, Longleg and the Clawstrider. That last one is particularly important as the Clawstrider is a powerful mount. This Cauldron also lets you craft overrides for the Skydrifter, Bellowback, Ravager, Snapmaw and the Rollerback.

Cauldron Gemini

Gemini is another story-based Cauldron. Much later in the story than Repair Bay Tau, you will come here as part of the main quest. If you happen across this desert Cauldron earlier, it won’t be accessible to you. Just progress further in the story to complete it and get the Sunwing override.

Cauldron Chi

These last two are the endgame Cauldrons. Chi is a level 30 Cauldron in the south-west of the map, in a bay south of Thornmarsh. The entrance is blocked, so go around to a cave on the right to enter.

Completing this high-level dungeon will unlock overrides for the Frostclaw, Redeye Watcher, Shell-Walker, Clamberjaw and Behemoth machines. You will also be able to then craft overrides for Stalkers, Shellsnappers, Spikesnouts, Scorchers, and Fireclaws.

Cauldron Kappa

Cauldron Kappa is the highest level of all the Cauldrons, and one of the most challenging parts of the game. It is a level 40 dungeon found in the north-west corner of the map, north of the greenhouse. This Cauldron is for completionists, so get levelled up if you plan on heading in. Speaking of entering, this Cauldron is entered underwater.

Conquering this final dungeon gives you the overrides for the Rockbreaker, Tideripper, Tremortusk and Stormbird machines. If those heavy hitters weren’t enough, you can also then craft overrides at the base for the Thunderjaw, Slitherfang, Dreadwing and Slaughterspine.
