Vile Ted and the Experiments is a multi-target boss encounter in Borderlands 4, fought during the side mission “Below the Surface.” Use this page when you need the Hydrus Sublab route, the Vile Armor priority, and the fast farm loop for Goalkeeper and Seventh Sense.

How to reach Vile Ted
Fast-travel to the Hydrus Sublab in the Terminus District of Dominion City and head east toward the facility. The encounter triggers during the side mission Below the Surface.
The fight: three targets, all with Vile Armor
“Vile Ted and the Experiments” is actually three enemies:
- CorrupTed — a Mutant Psycho
- Experiment 42 — a small Creep
- Experiment 1709 — a large Creep
Each one is protected by Vile Armor sitting over a Flesh health bar. Strip the Vile Armor first, then punish the exposed flesh underneath. Bring an element you’re comfortable swapping to against flesh, and watch your spacing — you’re managing three threats at once rather than a single boss.
Drops
Vile Ted and the Experiments has two dedicated legendary drops:
- Goalkeeper
- Seventh Sense
In addition, the Red Chest after the encounter has a small chance to drop a random world-drop legendary, and it resets every time you respawn the boss — so the Moxxi’s Big Encore loop is worth running for both the dedicated drops and the chest rolls. Weapon types, elements and stats vary by drop, so confirm them in-game.
