The Eradication Beamer is a directed-energy weapon mounted on Adeptus Mechanicus Onager Dunecrawlers. It fires a thin yellow beam that widens as it travels, atomising anything close and tearing apart targets further out at a molecular level.
What it does
The beam starts narrow and spreads as it projects outward, so the effect on a target depends on range. Anything caught up close is simply atomised. At middle distance, the beam ravages matter at a molecular level rather than instantly vaporising it.
That widening profile makes it a brutal area weapon against infantry formations. It doesn’t discriminate much between light and heavy targets at close range, though heavier armour further out will take less punishment.
On the tabletop
In 10th Edition, the Eradication Beamer is a ranged weapon with two profiles: dissipated and focused. The dissipated profile has a 36″ range, 3D3 attacks, BS 4+, Strength 9, AP -2, and Damage 2. The focused profile trades range for punch: 18″ range, 3D3 attacks, BS 4+, Strength 10, AP -3, and Damage 3.
Both profiles have Blast and Sustained Hits 1. Blast means you add one attack for every five models in the target unit, so it scales up against hordes. Sustained Hits 1 means each Critical Hit scores an extra hit, which rewards volume of fire.
The weapon can also be modified with options like Armour Piercing (AP+1), Brutal (S+1), or Heirloom (A+1), depending on how you want to tune it.
| Profile | Range | Attacks | BS | S | AP | D | Keywords |
|---|---|---|---|---|---|---|---|
| Dissipated | 36″ | 3D3 | 4+ | 9 | -2 | 2 | Blast, Sustained Hits 1 |
| Focused | 18″ | 3D3 | 4+ | 10 | -3 | 3 | Blast, Sustained Hits 1 |
Is it a disintegration weapon?
The exact mechanism isn’t explained in the lore, but there’s strong evidence it’s a form of disintegration weapon. Both are described as beams of energy that sever molecular bonds and reduce targets to atoms.
That overlap in language is suggestive rather than conclusive. The Eradication Beamer likely functions as a disintegration weapon at least in effect, even if the Adeptus Mechanicus would never confirm the details.
Where you’ll see it
The Eradication Beamer is part of the Adeptus Mechanicus armoury and shows up on Onager Dunecrawlers. It’s one of several weapon options for that walker, sitting alongside more specialised anti-tank or anti-infantry choices.
If you’re building a Skitarii or Mechanicus force, it’s worth knowing as a mid-range area weapon that can threaten both hordes and tougher units depending on which profile you use.
Key facts
- Mounted on Adeptus Mechanicus Onager Dunecrawlers.
- Fires a thin yellow beam that widens as it travels.
- Atomises nearby targets and ravages mid-range targets at a molecular level.
- In 10th Edition, it has dissipated (36″) and focused (18″) profiles, both with Blast and Sustained Hits 1.
- Likely a form of disintegration weapon, though this isn’t officially confirmed.
FAQ
What is the Eradication Beamer?
It’s a directed-energy weapon used by Adeptus Mechanicus Onager Dunecrawlers. It fires a widening yellow beam that atomises close targets and damages those further out at a molecular level.
What’s the difference between dissipated and focused profiles?
Dissipated has longer range (36″) but lower Strength and Damage. Focused trades range for punch, with 18″ range, Strength 10, AP -3, and Damage 3.
Is the Eradication Beamer a disintegration weapon?
It’s not confirmed, but the descriptions match closely enough that it’s widely considered a disintegration weapon in function, if not by official classification.
