Gauntlets of Leaping Lightning

While you wear both of these gauntlets, any
nonmagical weapon you grasp with either
gauntlet is treated as a magic weapon. As a
bonus action, you can use the gauntlets to
cause magical flames to envelop one or two
melee weapons in your grasp. Each flaming
weapon deals an extra 1d6 fire damage on a
hit. The flames last until you sheath or let
go of either weapon. Once used, this property
can't be used again until the next dawn.
