Crystal Dart

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 your Spell Modifier as 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.
