“Harrow Rod: The Twisted Conduit of Corrosive Arcana”
“Master the dark art of corrosion with the Harrow Rod, a potent magic rod that sprays deadly acid with terrifying precision.”

The Harrow Rod is a twisted black rod of metal, forged and enchanted by skilled practitioners of corrosive magics.

Tales speak of armies undone, walls eaten away, and vaults corroded from within, all under the influence of a Harrow Rod.
Beyond its raw destructive power, the rod carries a subtle aura of ambition: those who wield it are said to gain a heightened sense of strategy, learning to exploit weaknesses and act decisively. Over the centuries, the rods have been employed by cunning tacticians, ambitious wizards, and secretive operatives, their presence altering the course of conflicts and shaping legends in whispers across the land. Though simple in appearance, the Harrow Rod embodies a perfect union of craft, arcane skill, and calculated force—a tool that transforms careful planning into devastating results.

Forged by secretive alchemists and spellcasters, the Harrow Rod is a twisted black rod of enchanted metal, imbued with the power to corrode and dissolve matter at a distance. Legends speak of its use in sieges, clandestine operations, and duels of cunning, where its wielders turned the battlefield into a landscape of ruin. Though fearsome in effect, the rod also rewards careful strategy, as its destructive power is precise rather than indiscriminate.
