You quickly mutter a prayer and point to a foe sending forth a ray of searing light. You make a spell attack against a creature within range. On a hit, the target takes 4d8 radiant damage and must make a Constitution saving throw. On a failed saving throw, the target is also blinded until the beginning of your next turn. If an undead or a fiend fails this saving throw, it takes maximum damage from the spell in addition to being blinded.

At Higher Levels. When you cast this spell using a spell slot of 4th level or higher, the damage increases by 2d8 per spell slot above 3rd.
