Aunn's Fiery Gift

As an action you create 5 motes of fire that you grant to creatures within range. Until the end of your next turn, when a creature with a mote hits with an attack they can choose to expend a mote to deal 2d6 additional fire damage. No more than 1 mote can be expended per attack. All remaining motes expire at the end of your next turn, vanishing in a harmless puff of smoke.

When casting at higher levels you can grant 1 additional mote per spell level above 5th.
