Magmascope
How to listen to the magma beneath the Nether, find vents and break their crust in time with the pulse.
Magmascope looks not up but down — into a bowl of lava. Vents are found by ear.
Assembly
A three-by-three slab of heat-proof plates, the bowl-heart in the middle, two-block supports at the corners. It works only in the Nether and only with a full bowl: pour three buckets of lava by using a bucket on any part of the magmascope.
Hands-on
| What to do | How |
|---|---|
| Start observing | right-click the magmascope: your gaze drops into the bowl |
| Strike the magma | click — a ring spreads out from the crosshair |
| Hear a vent | when the ring reaches a vent it wakes an echo: the further the strike was, the wider and more shifted the echo |
| Clear the magma | strike almost point-blank — the vent’s crust becomes visible |
| Break the crust | the crust has its own pulse: rings converge on the rim. Strike the moment a ring reaches the rim |
| A miss | a strike off the beat heals one crack; a second strike on the same beat does not count, but is not a miss either |
While the crosshair is on the crust you can hear the pulse — strike to the sound. Every vent beats its own way.



Embers of the deep
Fiery bubbles drift in the magma — catch them to get deep embers. The fire road needs them just as the other two need stardust and void shards. At the bottom of the vents lie the worlds of fire, reached by the bell.
The diving bell
A found vent of the Forge opens the diving bell. It is built in the Nether over a lava pool at least three by three: the skirt goes right onto the lava — it stands just above the surface — then the dome, crown and winch on it (the layout is in the journal). A cryo still makes the coolant: click the bell with a canister, or pipe it to a launch gantry by the winch. Every dive from the Nether burns an ember-tempered chain, and the winch hauls the bell home for free. It is hot below — wear a suit with a Cooling Unit.
What next
- The worlds at the bottom of the vents have their own “Peoples and tasks”, “Dungeons and world masters” and “Gates”.
- A ship of the fire road goes out into the Depths: “Ships and space”.
- How the road ends — “End of the Fire Road” (behind spoilers).
