Wondrous Item, very rare
These alchemical-mechanical bracers are a masterpiece of craftsmanship — twin forearm-mounted weapon systems forged of black leather, steel, and adamantine. The right bracer conceals a spring-loaded dagger and dart launcher, while the left carries a micro-winch grappling spear and identical launcher array. When paired, they allow their wearer to act as both precision striker and mobile tactician — “a symphony of steel and science.”
