The Monolith is a Necron heavy support war engine: a floating slab of living metal that doubles as a troop transport, a gun platform, and a walking symbol of the dynasty that owns it. It matters because a single one can turn a quiet battlefield into a Necron beachhead in seconds.
What the monolith actually is
It’s a huge vehicle built from the same self-repairing living metal as the rest of the Necron arsenal. On the tabletop it fills the heavy support slot, and in the lore it works as transport craft, armoured destroyer, and power icon all at once.
The big crystal at its centre is the tell. When it lights up with that sickly green glow, the Monolith is either firing its main gun or opening the portal in its front face.
- Role: heavy support, transport, and terror weapon in one hull
- Material: living metal, which knits most battle damage back together
- Signature: a central crystal that pulses green when the Power Matrix is active
Armament and the Eternity Gate
Four Gauss Flux Arc projectors let it arc green lightning into every nearby unit, and that array can be swapped for a Death Ray. If it hasn’t just used its portal, it can dump the Power Matrix’s energy into a Particle Whip instead.
The portal itself, usually called an Eternity Gate, is a dimensional corridor linking the battlefield to a tomb world or an orbiting starship. Necron warriors cross huge distances and step straight into the fight. It’s also a weapon: on command it flips into a Portal of Exile, dragging anyone who can’t resist into a temporal prison.
| System | What it does |
|---|---|
| Gauss Flux Arc | Arcs of green lightning hitting every nearby unit; can be replaced by a Death Ray |
| Particle Whip | Main gun, fired by discharging the Power Matrix when the portal isn’t in use |
| Eternity Gate | Dimensional portal for deploying troops, or a Portal of Exile that banishes enemies |
Why it matters on the battlefield
Necron assaults often open with Monoliths teleporting down to act as a bridgehead, with the rest of the army marching out of their portals. That arrival alone makes them a problem before they fire a shot.
They’re also brutally hard to stop. The living metal shell repairs almost anything, so the only reliable answer is sustained heavy firepower concentrated on one spot until the armour breaches and the vitals underneath are exposed.
Monolith phalanxes and variants
The Ordo Xenos calls a group of two to five Monoliths a Monolith Phalanx. They teleport in together after a battle has already started, and at certain points in the four-dimensional universe they can emit a waveform that distorts space-time into a nodal grid, an energy field that makes the Necrons inside it almost impossible to destroy.
Sources differ on the details of the rarer configurations, such as the Nightshroud, so treat specific variant rules as edition-dependent rather than fixed lore.
Key facts
- The Monolith is a Necron heavy support vehicle made of self-repairing living metal.
- It carries four Gauss Flux Arc projectors, which can be swapped for a Death Ray.
- Its Power Matrix fires a Particle Whip when the portal isn’t in use.
- The Eternity Gate teleports Necron troops from tomb worlds or ships straight to the fight.
- Monoliths often lead an assault as a teleported bridgehead.
- Two to five Monoliths form a Phalanx, which can project a nodal grid that protects nearby Necrons.
FAQ
What is the Monolith in Warhammer 40k?
It’s a Necron heavy support war engine built from living metal. It transports troops through its Eternity Gate, hits hard with a Particle Whip and Gauss Flux Arcs, and repairs most damage it takes.
How do you destroy a Monolith?
You pour sustained heavy fire into one spot until the living metal shell breaches. Once the armour opens, the vital systems and crew inside are exposed and vulnerable.
What’s an Eternity Gate?
It’s the portal in the Monolith’s front face, a dimensional corridor to a tomb world or starship. It can also be reversed into a Portal of Exile that banishes enemies into a temporal prison.
