Angelic Rebuke

Even the darkest fiend cannot withstand the light of heaven.

With a word, you invoke the searing radiance of the higher planes to strike down your attacker. The targeted creature must make a Charisma saving throw. If they fail, they are blinded until the start of your next turn and take 2d10 radiant damage. If they succeed, they take half as much damage and are not blinded.

At Higher Levels. When you cast this spell using a spell slot of 3rd level or higher, the damage increases by 1d10 for each slot level above 2nd.
