Venerated Blade

You reach out and summon a glaive made of fire. It emits bright light in a 30-foot radius and dim light for an additional 30 feet. Weapon attacks made with it deal 1d10 force damage, as well as 2d4 radiant damage, and 2d4 fire damage.  As a bonus action on your turn, you can dismiss this spell and cause the weapon to emit a burst of flaming radiance. Each creature of your choice that you can see within 30 feet of the weapon must make a Constitution saving throw. On a failed save, a creature takes 2d8 radiant damage, 2d8 fire damage, and is blinded for 1 minute. On a successful save, a creature takes half as much damage and isn’t blinded. At the end of each of its turns, a blinded creature can make a Constitution saving throw, ending the effect on itself on a success.
