Amulet of Dragon Fire

Wondrous item, rare (requires attunement)

A bronze medallion etched with the coiling form of a flame-wreathed dragon. The metal is warm to the touch, and faint embers glow within its carved eyes. While wearing this amulet, once per day, you can exhale a cone of searing flame as if casting Burning Hands at 3rd level (save DC 15).
