Bonesand Slash

You conjure up a thick, twirling rift of sharp, bone-shaped rocks and sand around you. On this turn, you may use your action to make a melee spell attack against a target within 10 ft of you. If the attack hit, the target takes 2d6 slashing damage plus 1d6 bludgeoning damage and must succeed on a Constitution saving throw or be blinded for 1 minute.

At Higher Levels. When you cast this spell using a spell slot of 2nd level or higher, the bludgeoning damage and slashing damage both increase by 1d6 for each slot level above 1st.
