Brilliance

The caster's body briefly flares up into an intense shimmer of light, visible from up to 10 miles away. All creatures facing towards the caster within 50ft must succeed on a Constitution saving throw or be blinded for 1 minute. Creatures with sunlight sensitivity have disadvantage on this saving throw.

A creature blinded by this spell makes another Constitution saving throw at the end of each of its turns. On a successful save, it is no longer blinded.
