Blinding Smite (OneDnD)

Bonus Action taken immediately after hitting a creature with a weapon or an Unarmed Strike!

The target hit by the strike takes an extra 3d8 Radiant damage, and the target must succeed on a Constitution saving throw or have the Blinded condition until the spell ends. At the end of each of its turns, the Blinded target repeats the saving throw, ending the spell on itself on a success.

At Higher Levels. When you cast this spell using a Spell Slot of 4th level or higher, the extra damage increases by 1d8 for each slot level above 3rd.
