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 of the gem's
Charges are expended, the gem becomes a nonmagical jewel worth 50 gp.
