The Seepage Zone in the Silo is in the big room where you have to clear the Nest Sacs in the water. After clearing the sacs, you have to go through the barred doorway, where you will then come across a statue. You will enter the Seepage Zone after interacting with the statue.

Once you get into the Seepage Zone, you will find six statues in an underground anti-flooding facility. The trick to solving the puzzle lies in rotating the statues in a way so that they match their reflections on the water. Given below is the order to rotate:

Left statues:

• First statue: Rotate twice.
• Second statue: Rotate thrice.
• Third statue: Rotate twice.

Right statues:

• First statue: Do not rotate.
• Second statue: Rotate thrice.
• Third statue: Rotate thrice.

Upon aligning the statues correctly, a giant Deviation will come out of the reflection. Shoot the sac at its bottom to stun it, and then keep shooting the boil on top. After that, claim your loot and interact with the statue at the entrance to return to the Silo.

Once Human: How to get to the boss and fight it in Securement Silo Theta

Once you return to the Silo, turn right and run through a tunnel filled with black sludge. Keep in mind that your movement will be slowed by the gas spewers on the walls, and Gnawers will spawn from the sludge. You will also need to watch your Sanity, as the sludge reduces it.

Upon crossing the tunnel, you will reach a room with roots and green bulbs. Cross the room with the roots and take down the searchlights. Then you can enter the boss's room.

It is very easy to fight the final boss, Saint El. Just like other Elite Deviations in the open world, you have to shoot its legs to make it fall. Then keep shooting its head for critical damage until it goes down.

During the fight, stay on the elevated platforms as the room gets flooded with sludge. Gnawers also keep spawning, so you need to take them down quickly. Thus, Combat Deviations like the Mini Feaster will be helpful in this fight.

The loot chest spawns after Saint El dies, and keep in mind that there are other loot chests in the room. You can also get the Enchanting Void Deviant Companion in this dungeon.
