The device spawns 1d6 orbs of flame which levitate above your person. As part of casting, you may make a ranged spell attack against a creature or object in range by shooting one or more orbs. If you summoned multiple, you can shoot any number of them at the same or different targets in range. You must make a ranged spell attack roll for each orb you shoot. Each orb deals 1d4 + 1 fire damage.   Any orbs not shot when casting can be levitated above your person for the duration. You may use a future action to shoot any or all of the remaining orbs. If the space above your person becomes occupied or there is no space (a tight cave, perhaps), the orbs are extinguished and the device's effects cease. Orbs above you act as a lantern.
