Flamebreather Staff

This red, hollow quarterstaff releases a plume of fire when spun. When you hit with an attack using this magic weapon, the target takes an extra 1d4 fire damage. In addition, while holding the quarterstaff, you can speak its command word as an action to cause it to release a gout of flame from its end, duplicating the effect of the burning hands spell (save DC 13). This property of the quarterstaff can't be used again until the next dawn.

Versatile: This weapon can be used with one or two hands. A damage value in parentheses appears with the property—the damage when the weapon is used with two hands to make a melee attack.
