Blinding Radiance

Bright light erupts from your form and dazzles those around you. For the duration, you emit bright light in a 50-foot radius and dim light for an additional 50 feet. Each creature that moves within 10 feet of you for the first time on its turn or that starts its turn there must make a Constitution saving throw. On a failure, a creature takes 3d10 radiant damage and is blinded until the start of its next turn. On a success, a creature takes half as much damage and isn’t blinded.

At Higher Levels. When you cast this spell using a spell slot of 5th level or higher, the damage increases by 1d10 for each slot level above 4th.
