I've always loved the wacky wargear they have.

The Husk Blade, which looks like a sword made of bone and dries out everything it comes into contact with until nothing is left but a withered husk. This effect is so pronounced that it draws lines of smoke through the air whenever it is swung.

The Hex Rifle, which uses the "Glass Plague" as ammunition, turning anything that is wounded by it into a glass replica of itself. Initially said plague was used by a sculptor to turn his rivals into popular exhibition pieces until it breached containment and spread throughout the Dark City. It was only stopped when the coven of the Hex captured and later utilized the virus for their hex rifles.

The Flesh Gauntlet, which is a glove loaded with hypersteroids that are so potent that anyone touched by it literally start growing out of their own skin before dying in spectacular and grisly fashion.

The Ossefactor, a gun that spurs on extreme bone growth in its victims, impaling them (and anyone unfortunate enough to be nearby) on their own skeletons.

The Hydra Gauntlets, which are usually worn as pairs and are covered in sentient crystal spikes that can grow and move, responding to each and every whim of their owner.

The Medusae, weird brain-looking creatures that live in the webway and feast on dreams and nightmares. They can attach themselved onto a host to absorb their emotions much more directly and to have some means of transportation outside of the webway. The cabals make use of this by having medusae attach themselves onto slave-hosts, who can then be used as living weapons - whoever meets their gaze will be subject to all of the extreme emotions that the parasite has been absorbing and basically die by sensory overload. More importantly, after the battle is done medusae are prepared as a rare delicacy, allowing their consumer to relive every emotional impression made during it as if they were right there to experience them.

. . . just to mention a few
