Epicenter

Choose a point you can see within range. A ball of bright light erupts from the point to a radius of 60 feet, passing through walls and barriers and spreading around corners. Each creature within the radius must make a Constitution saving throw. On a failure, a creature takes 6d6 radiant damage and is blinded for 1 minute. While blinded in this way, fire damage deals double damage to the creature and it has disadvantage on saving throws against being poisoned or diseased. On a success, a creature takes half as much damage and is not blinded.

A creature can repeat its saving throw at the end of each of its turns, ending the effect on a success.
