Auralia’s Shrapnel Burst

You fire out a magically charged cluster of metal pieces in a straight line up to 60 feet. Upon contact with a physical object, the cluster bursts out in a 15 foot cone, dealing 4d6 points of slashing damage and 4d6 points of piercing damage. Any creature caught in the cone must make a dexterity saving throw, taking half damage on a successful save and full damage on a failed save.

At Higher Levels. When you cast this spell using a spell slot of 5th level or higher, the damage increases by 2d6 for each slot level above 4th, one for each damage type.
