Captain Willis is the last boss you’ll face in the first story pack for Borderlands 4, called ‘Mad Ellie and the Vault of the Damned’. This guide will tell you where to find him and show you what rewards he drops, helping you decide if the fight is worth it.
Here you’ll find Captain Willis’s location within the Maelstrom, plus details about his two Legendary items – Heimdahl and Reminisce – including who made them. We’ve included everything you need to know about this boss below!
Captain Willis Location & How to Beat in Borderlands 4
- Captain Willis is located inside the Maelstrom, which can be accessed through the Level Travel Station on the bottom right of the map, then by teleporting to the DNC Feuermann Bridge Fast Travel Station.
- Captain Willis can be farmed after the “Damnation Encroaches” final story mission for “Mad Ellie and the Vault of the Damned“.
- Captain Willis’s first health bar is Armor (yellow), so Corrosive and Cryo elemental damage is recommended.
- Captain Willis has a second health bar, which is Health (red), so Radiation and Shock will work wonders.
- When Captain Willis has both health bars depleted, you will need to use the grapple hook to pull off his exposed head to kill him.
All Captain Willis Loot Drops in Borderlands 4
| Legendary Item | Type | Special Effect |
|---|---|---|
| Heimdahl | Torgue Heavy Gun Ordnance | Rig – Fires Dahl soldier heads that attack nearby enemies. |
| Reminisce | Maliwan Shotgun | Remnant – Does not reload, and instead refills ammo when the projectiles return. |
Captain Willis, the final boss in Mad Ellie and the Vault of the Damned, doesn’t offer very impressive rewards. The Maliwan shotgun you get from him can be tricky and inconsistent, meaning you’ll need a very specific character build to make it worthwhile.
The Heimdahl Heavy Ordnance isn’t bad, but with so many other great Heavy Ordnance Legendary weapons (and critical strike knives) already available, it might not be worth the effort to farm for it.
