Now what self respecting Magical Girl doesn't have her signature weapon? Even Dark Magical Girls have them! They just prefer them to be more... Nasty.
Abyssal Bow: Opal's signature long bow used to be the harpoon and boat hook she would use to aid her captain and fish alongside her twin sister, but was twisted into coral and shells from the Abyssal Sea of the Envy Ring of Hell. When not in use, the entire weapon curls up inside the screw shell that adorns it, allowing Opal to carry it around as if it is just a simple good luck charm. When activated, the clam shell at the top opens, exposing a pearl charged with Malphesto's dark powers of Control. A crimson thread is formed from the pearl and connects to the base, allowing the mass to bend like standard wooden bows do. Should the thread break for any reason, Opal must close the clam shell and open it again. Just by pulling the bowstring as if nocking an arrow, Opal creates a sinister 'fishbone' arrow she can fire, and she may generate and fire as many arrows as she likes with each pull of the string based on speed or strength. Once fired, the arrow homes in on its target, and Opal may freely change each arrow's nature midflight or before firing, granting her a endless quiver of Green Arrow/Hawkeye Trick Arrows. Such is the danger of her being blessed by her Master's Control.
Mercurial Blades: Formerly the knives Lapis used to gut, clean and descale fish, as well as use during her time as a fisherwoman, the knives Lapis wields have been twisted and repurposed by her dark ascension under Malphesto's influence. Still used as intended, but now on people instead of fish, the blades have become semi liquid, allowing them to extend into longer blades when needed. The design remains the same, even as they change for situations where getting up close and personal may be problematic for her. Using her magic, she can make them like saws as they inflict wounds, or launch the blade directly from the hilt, instantly replacing it. But their darkest property is they have been re-forged from a blue mercury Lapis may solidify or liquidize at will. Much as the blades are under her full control, so too is any mercury that gets into her victim's bloodstream. Many a hero has screamed in horror as blades erupted from their friend's flesh before the metal returned to its Mistress and her weapon... When the daggers are not in use, they melt away, allowing Lapis to slip the lapis lazuli on their hilts under her wrist cuffs.
Desiccated Treant: Formerly the tree Jade called her home in her woodland where she met (And infuriated) her Dark God, the once vibrant black ironwood has been uprooted and turned into petrified, the spirit of the plant forever frozen in a silent scream in its shaft, and its lifeless branches fused to a stone blade. Where as Opal fights with finesse at range and Lapis with speed and grace up close, Jade only cares about raw power and chopping into her foes with a semi-blunted blade, so that she requires multiple swings to 'fell' the 'tree' she's hacking at. Despite its appearance, her axe is absurdly heavy, still bearing the weight of an fully grown black ironwood tree. If anything, the fact her axe can't make a clean cut into whatever it strikes only fuels her sadistic delight of drawing out the suffering of her victim, be it a hero trying to fight her Master, a tree, or someone that pissed her off. For Jade, she is the lumberjack, and all she sees is a forest waiting for her Master's order to clear cut. When not in use, her axe is very easily concealed in the jade at its base, which she keeps in a small pouch at her side. Granted, this only suits Jade's more primal and feral origins.
