Glimmer Gem

Wondrous item, legendary

This rare jacinth was first crafted by a wizard for use in his magic jar spell, yet when the fatal crack appeared, it caused the spell to go awry. The stone now draws the body and soul into it, projecting the soul to the astral plane. The body appears as a small sparkling speck within the gem and is reflected as a shade or shadow creature of its former self.

Any living being that comes within 10 ft. of the glimmer gem must make a successful DC 20 Fort save or be drawn into the gem. Victims of 4th level and below are instantly transformed into a shadow. Victims of level 4 and above must make a DC 20 Wisdom save. If this save succeeds they are instead transformed into a shade. Those failing the second save become shadows. Beings so transformed are trapped within a 500ft spherical proximity to the glimmer gem. Destroyed shades or shadows reform in 24 hours.

The glimmer gem may only be destroyed by a magic or adamantine weapon, or by means of magic spells such as disintegrate and shatter. It has AC 22 and 20 hp.

If destroyed, any beings trapped within the glimmer gem cease to exist, their spirits simply twinkling out. Beings turned to shade or shadow by the glimmer gem, and those destroyed when the gem is destroyed, may only be raised by means of true resurrection or wish.
