Walkthrough

1
Fast-travel to the Campfire north of Mother's Rise and head northeast to a fork.
2
Turn north at the fork, then northwest at the next fork to reach Mother's Crown.
3
In Mother's Crown, claim a Campfire and speak with a merchant named Grist.
4
Talk to Dral, south of the Campfire, to learn about Cauldron SIGMA and initiate the event.
5
Head to the northwestern end of Mother's Crown and find the northern gate. Near this gate, you'll find Training Dummy XVIII and Training Dummy XIX.
6
Before leaving town, speak to Solai, east of the northern gate, to learn about Nakoa and Daytower.
7
Exit Mother's Crown via the northern gate and cross the drawbridge. Find another Campfire.
8
Follow the trails and wooden platforms until you reach a fork. The northern path leads towards Hunter's Gathering, but for now, take a diversion northwest.
9
To the west of this road lies a Corrupted Zone. Destroy the three Corrupted Grazers within to clear the zone and earn 5,000 XP.
10
Backtrack southeast to the fork, then turn northeast until the road meets another road to the north. Light another Campfire.
11
Continue east, northeast, cross a bridge, then turn north. Ignore a path to the southeast and continue north to find the wreckage of a caravan where Marzavid starts the quest “Underequipped”.
12
Continue north to find another Campfire. Save your game.
13
Continue north along the road to a fork. Turn west, then southwest. Keep an eye to the north to spot Cauldron SIGMA, a triangular structure carved into the mountain.
14
Defeat the Watchers and Scrappers outside Cauldron SIGMA. Use tall grass for cover and stealth attacks.
15
Use your spear to override the door by holding down the [Triangle] button.
16
Enter the Cauldron and proceed through another triangular door to the north.
17
Loot a pyramidal Supply Crate to the east, then head northwest through a corridor of wires.
18
Cross a narrow beam and approach the glowing red triangle (vent) to interact with it.

Tips

Use the Lure Call and Silent Strike combo to easily defeat the Corrupted Grazers in the Corrupted Zone.
The area outside Cauldron SIGMA has tall grass, which is ideal for hiding and taking down enemies stealthily.
The [Triangle] button prompt to override the door is a bit of an ironic nod to the triangular shape of the Cauldron entrance.
