Thorn Growth

You force thorns to grow all over an enemy, creating a way to deal consistent damage over time. You make a melee spell attack against an enemy. On a hit, you deal 1d6 piercing damage. Additionally, for the duration of the spell, you can use a bonus action to reactivate this spell, dealing 1d4 piercing damage each time.

Any fire damage the target takes immediately removes the thorns. The target, or a creature within 5 ft of the target, can take an action to remove the thorns.

This spell’s damage increases to 2d6 and 2d4 piercing damage at level 5, 3d6 and 3d4 at level 11, and 4d6 and 4d4 level 17.
