Burrowing Ivory

Binding bone and sinew into a barbed needle, you launch it towards a creature you can see within range. Make a ranged spell attack. On a successful hit, the target takes 3d8 piercing damage and the needle embeds itself in the target’s body. While embedded in the target’s body, the needle magically burrows deeper at the beginning of each of the target’s turns. Each time the needle burrows deeper, the target suffers 1d8 piercing damage.

As an action, the target can painfully rip the needle from its body, suffering an additional 3d8 piercing damage and ending the spell. If the spell ends through any other means, the target suffers no additional damage.
