Chromatic Shivers

You conjure a spiked hexagonal prism of perfectly clear ice, which spins while emitting a full spectrum of colors as it shoots towards its target. A single color of light is emitted from its back end.

Make a ranged spell attack against the target. On a hit, the target takes 1d8 piercing damage. Hit or miss, the ice then explodes into small shivers, all with the one singular color corresponding to their elemental type. You choose fire, thunder, lightning, acid, cold, or poison for the type of shivers created. The target and all creatures within 5 feet of the it must succeed on a Dexterity saving throw or take 2d4 damage of the type you chose.

At Higher Levels. When you cast this spell using a spell slot of 2nd level or higher, the elemental damage increases by 2d4 for each slot level above 1st.
