Gauntlets of Flaming Fury

Requires attunement
While you wear both of these steel gauntlets, any
non-magical 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
ld6 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.
