Crystalline Slash

You emit a sharp crystalline protrusion from your body and strike at a creature that you can see within range. You choose force, necrotic, psychic, radiant, or thunder for the type of the protrusion, and then make a melee spell attack against the target. If the attack hits, the creature takes 3d8 damage of the type you chose.

At Higher Levels. When you cast this spell using a spell slot of 2nd level or higher, the damage increases by 1d8 for each slot level above 1st.
