Uncommon - Wondrous Item - Glass Globe

The driftglobe can be activated by speaking one of its command words, at which it will cast either the Light or Daylight spell as indicated by the user. The Daylight effect refreshes at dawn each day.

It can also be commanded, while it is illuminated, to float no more than 5 feet from the ground within 60 feet of the person who spoke the command, and will follow that person within 60 feet. If prevented from doing so, the light will go out and it will sink to the ground.
