Effect: The Gravekeeper's Lantern can temporarily trap a nonhostile spirit of the dead—either an incorporeal undead or the wandering spirit of a creature who died within the last 30 days—allowing you to interrogate them. Trapping a spirit requires you to be within 10 squares of them and succeed on a hard Intuition test as a main action. Once a spirit is trapped, you make a Presence test to coax them into answering your questions:
A trapped spirit remains in the lantern for 10 minutes. They remember being trapped by you, and might become hostile thereafter.
