Dungeon Master's Guide 5th Edition

Driftglobe

Wondrous Item Uncommon

Function

This small sphere of thick glass weighs 1lb. If you are within 60' of it, you can speak its command word and cause it to emanate the Light or Daylight spell. Once used, the daylight effect can't be used again until the next dawn.
You can speak another command word as an action to make the illuminated globe rise into the air and float no more than 5' off the ground. The globe hovers in this way until you or another creature grasps it. If you move more than 60 feet from the hovering globe, it follows you until it is within 60' of you. It takes the shortest route to do so. If prevented from moving, the globe sinks gently to the ground and becomes inactive, and its light winks out.  

History

Driftglobes date back at least to the time of Cormanthyr at its height and were seen lighting up the night in Myth Drannor. The arcanist Congenio Ioun created the first light-emitting ioun stones sometime in the age of Netheril but these were personal items that remained near their   Driftglobes could be found in use across the modern Realms, as well as in dungeons and ruins.

The most common driftglobes had three basic magical effects. They glowed with bright light, equal to a torch, as per the cantrip Light, on command. They could also glow with the brightness of full daylight, as per the spell Daylight for an hour at a time, though use of this ability was limited to a number of charges before being used up. Lastly, the driftglobe floated in the air, as per the magical spell Levitate. A driftglobe could also follow a creature that touched it, similar to the disk created by Tenser's floating disk(DnD3e). A driftglobe was a small sphere of thick glass, that weighed about one pound (0.45 kg).

Creation

Driftglobes were quite easy to make, and the process was well known. A caster needed little more than a glass globe and the ability to cast Daylight and Tenser's floating disk.
