Deathly Smite

The next time you hit with a melee weapon attack on the same turn you cast this spell, your attack deals an extra 2d8 necrotic damage. Additionally, if the target is a creature that is not resistant or immune to necrotic damage, it must make a Constitution saving throw or be blinded until your next turn.

At higher levels: When you cast this spell with a spell slot of 2nd or higher, the spell deals an additional 1d8 necrotic damage for each slot above 1st.
