The Soulcage is a small, lantern-like object that is designed to entrap a soul shortly after death before it travels to the Raven Queen's domain. It's constructed using necromantic energy and generally is considered to be a morally... grey item to possess. However, it does have some uses.

In order to trap a soul within, a ritual lasting 1 hour must be performed, ending with the death of a being with intelligence above 6 (the one whose soul is to be trapped). Any creature that has had its soul trapped within a Soulcage cannot be resurrected by means short of a Wish or Miracle spell, nor contacted by spells such as Speak with Dead.

The Soulcage acts as a Lantern of Revealing, providing bright light for 30 feet and dim light for another 30. Invisible creatures and objects are visible so long as they are in the lantern's bright light.

The Soulcage may also be used as a magical focus by druids, sorcerers, or wizards giving a +1 bonus to spell attack rolls and spell save DC of your class' spells.

The soul within will be free to travel to the Raven Queen's domain if the cage itself is destroyed.
