Ultima-Pattern Arbites Maul

Ultima Pattern Shock Maul used by the Adeptus Arbites

A Shock Maul or Power Maul is a type of Shock Weapon. Shock Weapons are designed to be generally non-lethal, assaulting the victim with incapacitating force through electrical shocks released on impact. As Shock Weapons have little or no destructive impact on flesh other than minor electrical burn marks, they are useful for crowd control and “encouraging” workers such as shipboard press gangs or other forced labour. A Shock Maul resembles a club surrounded in an electrical energy field which disrupts the surface of solid matter. The depth of the field can be adjusted to bash a hole through a wall or merely administer an irresistible knock-out blow to subdue a victim. The electrical energy that is discharged can cause severe burns on impact and can disrupt the nervous system. Unlike the Power Axe, the maul is always held in one hand, leaving the other hand free for a pistol, riot shield or other weapon. These fearsome weapons are most commonly found in the hands of the Adeptus Arbites and local enforcer squads on countless Imperial worlds who enforce local and Imperial law. While they are intended for crowd control and riot suppression, in the hands of an enthusiastic user they can also be deadly combat weapons.

Shock Maul VariantsEdit

  • Agni Pattern Power Maul - A relatively small and inexpensively manufactured model of Power Maul, this weapon is weighted towards the hilt, and as such is regarded by some Power Weapon connoisseurs as somewhat graceless. It is common in "second line" precincts (as they are locally known) where trouble is not particularly expected, or among vehicle crews who value its handy proportions. Like all true Power Mauls, it has energy settings which can be adjusted to the circumstances.
  • Bone Maul - This two-handed melee weapon is commonly found amongst the feral tribes on the Writhing World. Each dull grey bone maul is covered with runic etchings created by that world's biomancers and stains of ancient flesh and blood. Each is also much heavier and stronger than any weapon crafted from normal bone. With each bloody impact the maul becomes cleaner and brighter than when the battle began, until the foe is dead and it appears as gleaming ivory. After the battle it slowly tarnishes again, until it returns to its original dull grey colour.
  • Cyclopea Pattern Power Maul - A huge and intimidating two-handed weapon unique to the Calixis Sector, this Power Maul contains a monstrously overcharged disruption field which actively shatters the bonds between the molecules contained within items it strikes. Resembling a feudal mace, this maul has only one power setting: maximal. Potent enough to crush groundcars or send shattered opponents flying dozens of feet with a single stroke, this weapon is reserved for the most intense riots. It is designed to awe and terrorise the enemies of the Adeptus  Arbites, and to send entire mobs cowering before the user.
  • Lathe Pattern Power Maul - A light, slender, and elegant model of Power Maul, this unusual weapon (crafted only on demand in the Calixis Sector) has a spiked handguard and a long, straight, un-weighted haft. It must be handled more like a sword than a club, which some users find frustrating, and critics have labelled the weapon fussy and difficult to master. However, the Arbitrators manning the Precinct Fortresses of the Lathe Worlds find that the slender profile is highly effective in the dense corridors of the manufactoria. Those who take the time to familiarise themselves with the pattern's idiosyncrasies declare it one of the finest examples of a Power Maul ever made. The apparent fragility of the design is misleading, and the versatile power field is more than capable of inflicting the same damage against opponents as models with a more brutal heft.
  • Ultima Pattern Arbites Power Maul - This pattern of Power Maul is a versatile, one-handed weapon with two power settings. At its low setting, the maul's head delivers an electrical shock powerful enough to stun (and sometimes kill) its targets, just like a regular Shock Maul. At the high setting however, the energy forms a crackling power field that can sunder steel, armour, and flesh. The Power Maul of the Adeptus Arbites is as much a symbol of Imperial authority as it is a weapon, and one that is seared into the minds of petty criminals and serious recidivists alike. While rank-and-file Arbitrators make do with simple Shock Mauls, veteran Proctors or the feared Judges prefer to wield the far more impressive Ultima Pattern Power Maul.
