Crystalline Cone

As you hold your hands with thumbs touching and fingers spread, a thin sheet of crystals and gems shoots forth from your outstretched fingertips. Each creature in a 15-foot cone must make a Dexterity saving throw. A creature takes 4d6 slashing damage on a failed save, or half as much damage on a successful one.

A Creature caught in this blast must also make a Constitution saving throw (DC14), or suffer the Blinded condition for 1 minute.

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