Item from Arcane by Riot Games
Jayce's signature hextech-powered weapon that seamlessly transforms between a devastating warhammer and a long-range energy cannon, embodying Piltover's fusion of elegance and destructive innovation.
The Mercury Hammer is Jayce's proof of concept — evidence that hextech can be more than industrial tools and trade infrastructure. It transforms between melee and ranged configurations with fluid mechanical precision, each mode drawing on the same hextech crystal in fundamentally different ways. As a hammer, it channels energy into kinetic force that can shatter stone. As a cannon, it focuses that energy into concentrated arcane bolts. The weapon made Jayce a symbol of Piltover's might and a target for its enemies. He wields it with increasing reluctance, a scientist forced to become a warrior because the world he helped build keeps demanding violence.
A sleek warhammer of polished silver and gold with hextech circuits running along its haft. A blue hextech crystal pulses at its core. In cannon mode, the head unfolds into an elongated barrel that charges with crackling arcane energy before firing.
