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.
