Blood Blades

You send forth blades of blood to attack a creature within a 60-foot cone originating from you. A creature within the cone must make a Dexterity saving throw. On a failed save, the target takes 1d10 slashing damage.

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