Lantern of Tracking

From Icewind Dale: Rime of the Frostmaiden, pages 314-315.

Description
Wondrous item, common.

This hooded lantern burns for 6 hours on 1 pint of oil, shedding bright light in a 30-foot radius and dim light for an additional 30 feet.

Each Lantern of Tracking is designed to track down a certain type of creature, which is determined by rolling on the Lantern Tracking table. Once determined, this creature type can't be changed. While the lantern is within 300 feet of any creature of that type, its flame turns bright green. The lantern doesn't pinpoint the creature's exact location, however.
