The power maul is a power weapon that works like a high-tech baton: a blunt club wrapped in a power field. It’s the go-to crowd-control tool of the Adeptus Arbites, and Space Marines swing them too when they want something broken rather than sliced.
What the power maul actually does
Strip away the imagery and it’s a baton with a power field around it. That field disrupts whatever it touches, so a swing that would normally just bruise can punch a hole through a wall instead.
The clever part is the dial. The field setting can be adjusted from a full demolition-grade bash down to a controlled knock-out blow on one person. That range is exactly why Imperial law enforcement loves it: same weapon, different job.
Who carries one
Adeptus Arbites shock troops are the classic users. They pair the maul with a suppression shield, which is about as clear a statement as you can make that a riot is about to end badly for someone.
Adeptus Astartes also field power mauls, though usually as a specialist pick rather than a standard sidearm. Inquisitors, enforcers, and other Imperial agents show up with them too.
Patterns matter more than you’d think
Not every maul handles the same way, and the differences change how you fight with it.
The Ultima pattern is short, heavy, and plain. It’s built for choppy strokes and works fine as a plain truncheon even with the field off, which is a polite way of saying it breaks bones either way.
The Hydraphur pattern goes the other direction: longer, lighter, slimmer, with a spiked handguard that gets in the way of reverse-grip work. It lacks the weight to just club people down, so users fence with it, jabbing with the tip and letting the power field do the damage.
| Pattern | Build | Fighting style |
|---|---|---|
| Ultima | Short, heavy, unadorned | Choppy strokes, works as a plain truncheon |
| Hydraphur | Longer, lighter, spiked handguard | Fencing jabs; needs finesse, not muscle |
Power maul vs shock maul
These two get confused constantly, and it’s an easy mistake. A shock maul does its work with an electrical discharge, not a power field. It’s built to incapacitate, not to wreck.
A power maul is the heavier concept. It can knock someone out, sure, but it can also go through masonry. If you’re picturing sparks and twitching, that’s the shock maul. If you’re picturing a wall losing an argument, that’s the power maul.
Notable power mauls
A few named mauls have real weight in the lore, mostly because of who swung them.
Worldbreaker belonged to Horus Lupercal, and Illuminarum was Lorgar’s. On the loyalist side you’ve got the Weight of Duty with the Hammers of Dorn, the Lost Mace of Corswain among the Dark Angels, and Axiom with the Iron Hands.

FAQ
Is a power maul the same as a thunder hammer?
No. A thunder hammer is a dedicated anti-armour and anti-monster weapon built around a massive impact. A power maul is smaller, more controllable, and designed for crowd control and law enforcement as much as combat.
Can a power maul kill, or is it non-lethal?
It can absolutely kill. The adjustable power field lets a user dial it down to a knock-out blow, but at higher settings it’ll go through walls, and even unpowered it’s heavy enough to break bones.
Who uses power mauls in Warhammer 40k?
The Adeptus Arbites are the main users, typically alongside suppression shields. Space Marines and various Imperial agents also carry them, though usually as a specialist choice.
