Kuku Bismuth Spear
A bismuth spear reinforced with a kuku spear. By using the pot to condense bismuth ores to their absolute limit, every swing of the spear causes newly formed resolutions to burst forth in all directions. It also retains its ability to petrify enemies, slowing them down as if they were turned to stone.

Aeserion Spear Wearer: All Characters A spear made with the scales of Aeserion, the Great Serpent. The scales used for this weapon are imbued with a power not of this world. The benevolent god bestowed wisdom upon people in the distant past, and today, he has even offered scales containing his power. This is because he loves the inhabitants of Pywel more than anything else. 
Reckoning Wearer: All Characters A massive spear once wielded by Titan, the God of Lightning. Though its lightning power faded when it left its original owner's hands, the spearhead, shaped like a bolt striking down, remains as sharp as ever. 
Electro-Mecha Spear Wearer: All Characters An electricity-charged spear used by Marni's Machina Knight. Rather than a standard spear, Marni fitted it with a special device to make the blade conduct electricity. Anyone struck by it suffers not only the spear's damage, but the shock from the electricity as well. A brief recharge time is required after an attack. 
Elite Vanguard Wearer: All Characters A charging lance used by the elite cavalry of the Wells Estate. Its long, slender tip is honed to slip into the seams of armor, while the petal-shaped metal leg base spreads the impact of a hit, protecting the rider's wrist and the lance's shaft. 
Frostfang Wearer: All Characters A spear once wielded by Gwen Kraber, second-in-command of the Wolf Trackers. Its tip is long and straight, like the fang of a beast. With a steady grip, she would drive it home, freezing the very blood and breath of her prey. 
Kuku Disruptor Spear Wearer: All Characters A disruptor spear reinforced with a kuku spear. The original disruptor spear was limited by its own internal mechanisms, which necessitated a cap on its power output. However, the kuku pot, forged with Abyss technology, removes these constraints, allowing the weapon to freely unleash waves that disrupt mechanical operations. 
Kuku Flame Spear Wearer: All Characters A flame spear reinforced with a kuku spear. The pot is packed with high-concentration fuel, unleashing a wave of all-consuming flame with every swing. Though persistent overheating issues prevent it from spewing flames indefinitely, it remains a weapon of formidable power. 
Kuku Laser Cannon Spear Wearer: All Characters A laser cannon spear reinforced with a kuku spear. It functions less like a spear and more like a portable cannon that fires explosive beams. Power amplified within the pot erupts from the tip as a streak of light, piercing through any enemies in its path.
