Blinding Smite (Revised)

As part of the action used to cast this spell, you must make a melee attack with a weapon against one creature within the weapon's range, otherwise the spell fails. On a hit, the target suffers the attack’s normal effects, and your weapon flares with a bright light; the attack deals an extra 3d8 radiant damage to the target. Additionally, the target must succeed on a Constitution saving throw or be blinded for 1 minute.

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.

At higher levels: When you cast this spell using a spell slot of 4th level or higher, it deals an additional 1d8 radiant damage for each level above 3rd that it is cast.
