Owlboy Lava Boss Guide: How to Beat the Hex Machine

A complete Owlboy lava boss guide covering the route to the lava arena, the Hex Machine's hop and whip attacks, and how to finish the fight with both outlets.

Which Boss Is the Owlboy Lava Boss?

Owlboy has two encounters that players tend to lump under this label. The Lava Worm appears earlier in the adventure and gets name-dropped frequently on the Owlboy Steam Community forums. The fight most people mean when they search for the owlboy lava boss, however, is the Hex Machine — a hulking red-and-black construct that Otus, Geddy, and Alphonse face in a molten cavern beneath the Floating Continent. The full encounter, from the jungle approach to the final electrocution, is documented in The Basement's Owlboy Let's Play, Part 23 on Nintendo Switch.

How to Reach the Lava Arena

The road to the lava boss starts in the Floating Continent jungle, after the puzzle where you rotate the giant owl clock gears. Progress along the linear pathway, and keep these route notes in mind:

Hidden paths matter. The Let's Play hosts get stuck looping through the jungle because an unmarked side passage opens the way forward. If you are running in circles, look for bush-covered switches and off-color walls.
The locked gate has a torch solution. A tip from the Owlboy subreddit, quoted in the video, says to shoot the skull torch off its perch — Alphonse's shotgun does the job — which releases the gate lock.
Drop down once the tunnel opens. After the gate, a new shaft leads into the cavern where the lava finally appears. The pirate Twig and his former comrade Dirk show up for a cutscene, and Twig wakes the machine with the line "Boot sequence initiated... protect the Hex Machine. Destroy all interloping agents."

Phase One: Surviving the Hex Machine

The Hex Machine hits hard and controls the whole arena — the hosts repeatedly note that you cannot go around, over, or above it. Staying alive means reading three core attacks:

Attack	What It Does	How to Counter
Hop slam	Leaps across the lava floor and crashes down	Stay low and sneak underneath as it hops; resist the urge to fly
Whip arm	A long, "licorice" whip lash that covers huge range	Very hard to dodge mid-air — keep grounded and bait it early
Slime barrage	Sloppy, slimy projectile spray that chunks your health	Keep moving and swap to Alphonse for higher damage output

Practical tips from the run:

Fly less than you want to. The hosts learn this the hard way; hovering invites the whip.
Focus fire on the module on top of its head. That is where damage counts, and once it is exposed the top can be pressed down like a button to close a circuit.
Grab health pickups when they appear — the fight is long enough that the extra health matters.

Phase Two: Close the Circuit with Both Outlets

Pressing the head module down looks like a kill, but the machine revives — "another is not dead yet," as the hosts put it. The true finish requires the arena itself. The in-game hint reads: "Activating both outlets will shock the Hex Machine to death."

Find the two differently colored wall panels in the chamber.
Trigger each outlet (Geddy's smooth, green swirly shot animation is the tell that an outlet is live).
Once both are activated, the machine is electrocuted for good, and a cutscene introduces a spider-like figure trapped inside — who, notably, is not hostile and calls Dirk a former comrade.

How Hard Is the Fight? What Players Say

Difficulty is the defining conversation around Owlboy's bosses. In the long-running "Skip boss fights?" Steam thread, the original poster describes finishing the Monkey King boss, passing through the lava section, and going "straight into another bloody boss," asking D-Pad Studio for an optional skip. Other posters chime in:

One player returning after a break calls loading back into the Lava Worm boss fight "infuriating," while another names the lava worm among the bosses they "quite liked."
A commenter praises the game's pacing otherwise — "checkpoints everywhere, neither too easy nor too difficult" — which softens the sting of retries.
The Monkey King's flunkies draw special ire for grabbing Otus and dragging him into lava, though one player beat them by hovering over gaps and letting enemies drop into the molten pits.

The takeaway: the lava boss encounters are pattern-learning checks. Watch the tells, stay grounded, and retries are short thanks to generous checkpoints.

Owlboy Lava Boss FAQ

Is the Owlboy lava boss the Hex Machine or the Lava Worm?

Both get the nickname, but most searches lead to the Hex Machine in the lava cavern below the Floating Continent. The Lava Worm is an earlier lava-themed boss that some players remember fondly.

Can you skip the lava boss fight?

No. There is no built-in skip or easy mode, and a popular Steam thread requesting one has not changed that. Checkpoints keep each retry brief.

How do you damage the Hex Machine?

Shoot the module on top of its head — Alphonse's shotgun deals solid damage — then press the module's top down like a button to close the circuit. Stay low and slip under its hops rather than flying.

Why won't the Hex Machine die after the head module?

Closing the circuit only downs it temporarily. The real kill is environmental: activate both outlets on the arena walls so the machine is electrocuted.

What happens after the fight?

A cutscene plays, revealing a spider-like prisoner inside the machine who recognizes Dirk as a former comrade. From there, the story continues deeper into the Floating Continent — and, as the Let's Play hosts joke, you have officially "been hexed."
