Crystal Missile

You create a large crystal of solid magic. The crystal hits a creature of your choice that you can see within range. The crystal deals 3d4 + 3 piercing damage to its target. If the target survives, the crystal fades from existence. If the target dies, the crystal explodes and deals 1d4 piercing splash damage to individuals within 5 feet, excluding the caster.

At Higher Levels. When you cast this spell using a spell slot of 2nd level or higher, add 1d4 + 1 for each slot level above 1st.
