Arcane Artillery

You create three large projectiles (shells) of magical force. Each projectile hits a creature of your choice that you can see within range. Each shell deals 3d12 + 4 force damage to its target. Any creature within 10 feet of a target must make a dexterity saving throw and take damage equivalent to the target upon a fail against your spell save DC otherwise taking half damage upon success. The projectiles all strike simultaneously, and you can direct them to hit one creature or several.

At Higher Levels. When you cast this spell using a spell slot of 6th level or higher, the spell creates one more shell for each slot level above 5th.
