• Magical Item – Uncommon – Gem of Brightness – 200 gp
  • Standard: This prism has 50 charges. While you are holding it, you can use an action to speak one of three command words to cause one of the following effects.
    • The first command word causes the gem to shed bright light in a 30-foot radius and dim light for an additional 30 feet. This effect doesn’t expend a charge. It lasts until you use a bonus action to repeat the command word or until you use another function of the gem.
    • The second command word expends 1 charge and causes the gem to fire a brilliant beam of light at one creature you can see within 60 feet of you. The creature must succeed on a DC 15 Constitution saving throw or become blinded for 1 minute. The creature can repeat the saving throw at the end of each of its turns, ending the effect on itself on a success.
    • The third command word expends 5 charges and causes the gem to flare with blinding light in a 30-foot cone originating from it. Each creature in the cone must make a saving throw as if struck by the beam created with the second command word.
  • When all the gem’s charges are expended, the gem becomes a non-magical jewel worth 50 gp
  • Attunement: While attuned, every full cycle of the moon it is attuned it regains 5 charges on the night of the full moon or 10 if it is the night of the red moon.
  • Relic: When held by a dragon, it also regains one charge each week it has been attuned.
