Blessed Flame

You call down a column of blessed flame on a target you can see within range. The target must make a Dexterity saving throw. On a failed save, it takes 6d8 radiant damage and is Blinded until the end of your next turn. The target takes half of the damage on a successful save and isn’t blinded. Undead and fiends have a disadvantage on this saving throw. At Higher Levels: When you cast this spell using a spell slot of 5th level or higher, the radiant damage increases by 1d8 for each slot level above 4th.
