Singing Oil. This silvery-gray oil is flecked with shreds of iron and tin, and it rings melodically as it swirls inside its container. When used, the oil produces a range of harmonic chords at a pleasant volume and soaks into the weapon, which gives off a humming sound for the duration. While the weapon is drawn, the sound can be heard up to 60 feet away.

Notes: Damage: Thunder, Buff, Consumable
