1. Drop Down to the Entrance

Enter the dungeon, turn left, and go through the door ahead.

Carefully drop down the ledges and pass through the bricked archway.

2. Destroy All 3 Black Ulcers

Search the underground passage for 3 Black Ulcers and destroy them, taking down any enemies in your path.

Don't Step on the Black Goo on the Ground

There’s a lot of black goo on the ground in this passage. Avoid stepping on it, as it quickly drains your sanity.

3. Destroy the Nest Sac in the Underground Passage

Press forward after destroying all the ulcers, then turn left when you reach a pile of junk surrounded by Gnawers.

Continue ahead, then make another left to find a couple of Gnawers and a Nest Sac at a dead end. Destroy both the Nest Sac and the Gnawers surrounding it, then retrace your steps.

4. Destroy All 3 Nest Sacs in the Water

Move forward and go up the stairs to your right to reach a large room. Destroy all 3 Nest Sacs on the water along with the Gnawers surrounding them.

From this room, you can either go left through the narrow passage to continue to the end of the dungeon, or go to the seepage zone.

5. Avoid the Spitting Deviants in the Narrow Passage

Continue through the narrow passage while avoiding the fumes spewing out of the deviants on the wall.

You can reach the other side of the room by jumping on the drums to stay clear of the black goo on the floor.

6. Cross the Tumor-Filled Room

Next, follow the hallway to a tumor-filled room. Use the broken pillars and the pipes to get to the other side.

Don't forget to grab the Gear Crate before you leave the room!

7. Defeat Saint El

Pass through the tunnel to reach the last room where you need to fight Saint El.

Defeat Saint El, then grab your loot before leaving the dungeon.

Aim for the Glowing Spots on Its Legs

You can defeat Saint El quickly by aiming for the glowing weakspot on its legs. Utilize the pillars in the room to stay clear of the projectile it throws at you.

Chagas Weevil can also spawn other enemies in the room, so make sure to take them down too!
