Sunfire Amulet

Wondrous Item, Rare (Requires Attunement)
The Sunfire Amulet is a radiant amulet that contains a captured fragment of the sun's energy. It glows with a warm light, illuminating the area around the wearer in a 15 ft. radius and instilling a sense of confidence and resilience.
Radiant Burst: Once per day, as an action, you can unleash a brilliant burst of light from the amulet. Each creature of your choice within a 15-foot radius centered on you must make a Constitution saving throw (DC 12) or take 1d8 radiant damage. On a failed save, the creature is also blinded until the end of its next turn.
