Erik's Quills

The caster conjures and throws 2d4 porcupine quills at a target they can see within range. Only one ranged spell attack is needed. On a success, its target takes 1 point of piercing damage for every quill, and 1 additional point of damage at the beginning of each of their next 3 turns.

Leveling: The number of quills the spell creates increases by 2d4 when its caster reaches 5th level (4d4), 11th level (6d4), and 17th level (8d4).
