You hang this lantern on the empty air, where it floats under your command.
Wondrous Item 680 gp
This lantern casts light in a 10-square radius, and it never needs lighting or refilling. When you let go of the lantern, it continues to hang in the air where you leave it. If weight in excess of 1 pound is applied to the lantern, it falls to the ground.
Any creature holding the floating lantern or adjacent to it can set its light to be bright (10-square radius), dim (5-square radius), or off as a minor action.
As a move action, the last creature to hold the lantern can mentally command it to move up to 10 squares in any direction, but not more than 10 squares from the commanding creature.
