Force Weapon - Force Weapon: Force Weapons are advanced, psychically-attuned close combat weapons that are only effective in the hands of a psyker. Force Weapons effectively act as deadly, psychic extensions or amplifiers of the wielder's own Empyrean-spawned powers. They are designed to allow a psyker to channel deadly Warp energies into their target, acting as a conduit between the wielder's mind and the flesh of their target. Large alien monstrosities and Daemons that are resilient to conventional weapons can be slain outright by a single wound from a Force Weapon, as their bodies and minds are destroyed by the unearthly powers of the Immaterium.Force Weapons take the form of swords, spears, warhammers, axes, staves or other close combat melee weapons. Within the structure of the weapon is interwoven a powerful device called a Psi-convector, formed into a precise serpentine shape which concentrates and directs psychic energy. This device sometimes appears as a decorative pattern on the blade.Force Weapons are hand-crafted to the user's specifications, quite often by the user themselves, and the psyker's first challenge once the weapon is complete is to attune it to themselves, to learn to channel their power through it without risk to themselves or their allies and surroundings. Mastering a Force Weapon is a difficult task for even the Space Marine Librarians, but the ultimate reward is well-worth the risk, for a psyker channelling their power through their Force Weapon can strike the most powerful of foes down in one fell stroke.Once mastered, each Force Weapon is intimately attuned to its wielder's mind, and another psyker trying to wield it will find it a daunting, if not impossible task. Force Weapons are treasured possessions to their wielders, and will quite often accompany them in death, being buried or cremated alongside their owner.A Force Weapon can be wielded without risks by a non-psyker, but in their hands, it will have none of the mighty abilities it displays in the hands of a psyker. Unlike Power Weapons, the power of a Force Weapon comes from the psyker's mind, and not some technological contraption sacred to the servants of the Machine God embedded in the weapon's hilt. Exceptional psykers can lend their weapon to a non-psyker and still channel their power through it, for such is their intimacy with their weapon that physical contact is no longer necessary to employ its powers.A notable example of a unique Force Weapon is Inquisitor Gregor Eisenhorn's Runestaff, a steel staff topped with a thirteen-pointed sunburst made out of electrum. In the centre of the sunburst is a skull made out of psy-reactive crystal etched with the thirteen Runes of Castigation.Other well-known Force Weapons are the Force Warhammers or "Daemonhammers", the signature weapon of the Inquisitors of the Ordo Malleus, which provided that branch of the Inquisition with its High Gothic name. Force Weapons are one of the few weapons that can seriously damage Daemons and Daemonhosts and are often used by the members of the Ordo Malleus for that reason.Force Weapons are also often used by Craftworld Aeldari Warlocks and Farseers, who use their Witchblades and Singing Spears to devastating effects on the battlefield. Aeldari Force Weapons are grown from the psycho-reactive substance known as wraithbone, and are often of superior craftmanship and efficiency compared to their Imperial counterparts, but the basic principle of the psyker channeling their power through their weapon remains the same for these xenos constructs.
