Fell Spines

Flesh and bone obey your command and form spines along your forearm. Flinging your arm out, you launch the bony projectiles into your opponents. Choose a number of targets up to your proficiency bonus in a 15 foot cone. Each must make a Dexterity save or take damage equal to your basic melee damage and become rattled until the start of its next turn. This damage is considered both necrotic and piercing. On a successful save, the target does not take the damage, but is still rattled until the start of its next turn.
