Primordial Vault: Fadefields Walkthrough

Kill All Enemies

# Walkthrough
1
Borderlands 4 - Start Vault of Inceptus
Enter the rift and interact with the glowing stele to begin the Vault of Inceptus.
2
Borderlands 4 - Kill All Enemies
When you enter the Vault of Inceptus, you will be faced with three waves of enemies in three segments of the Vault, all leading to the boss at the very end.
3
Borderlands 4 - Step on Launchpad
Clear each stage of enemies to progress through the Vault. Step on the glowing yellow pad to be launched to the next stage.
4
Borderlands 4 - Inceptus Vending Machines
Before reaching the boss arena, you will come across a checkpoint with Vending Machines. Refill ammo and buy Repkits as needed. This is especially helpful in the event that you die repeatedly to the Vault boss.

Defeat Inceptus

# Walkthrough
1
Borderlands 4 - Primordial Guardian Inceptus Battle
At the end of the Vault, you will face the boss Primordial Guardian Inceptus. Inceptus is weak to Shock and Incendiary damage.
*
Borderlands 4 - Inceptus Pull Out Lump
During the fight, you will notice that you will be prompted to use your grappling hook on Inceptus. Use the grappling hook to pull lumps out of Inceptus' limb joints. Shoot these lumps to deal extra damage.
*
Borderlands 4 - Inceptus Projectiles
Inceptus' go-to attack is shooting a swarm of radioactive projectiles that easily cover the arena. Coming into contact with them will cause them to explode and hurt you. Shoot them from a safe distance before they detonate.
*
Borderlands 4 - Inceptus Cocoon
Borderlands 4 - Shoot Lumps on Cocoon
At some points during the fight, Inceptus will rise and wrap itself into a cocoon that will spew Radiation all over the arena. Staying on the ground will kill you due to damage received over time.

To avoid this, look up and use your grappling hook to reach for the hanging baskets. At that height, you can shoot the lumpy area on top of the cocoon to deplete its health bar and resume the fight with Inceptus.

Note that you cannot stay on one basket for too long as it will lower due to weight. Jump to other nearby baskets to shoot the cocoon.
2 After killing Inceptus, enter the rift to be taken to the next area where you will claim your reward.
3
Borderlands 4 - Inceptus Glide Upgrade and Weapons Chest
Interact with the golden orb to receive an upgrade for your Glide Pack. Up ahead, open two weapon chests before leaving the area through another rift. You will be transported outside of Inceptus' boss arena.

Primordial Guardian Inceptus Drops

Optional: Re-Farm Inceptus

Borderlands 4 - Inceptus Moxxi

You may replay the boss fight with Inceptus to obtain more rewards. Spend money at Moxxi's Big Encore Machine, located in front of the boss arena, to fight Inceptus again.
