The next time you hit a creature with a weapon attack before the spell ends (Concentration, 1 min), a mass of magical vines erupts from the ground around the target. The target makes a STR save or becomes Restrained. A Restrained creature takes 1d6 Piercing damage at the start of each of its turns and can use its Action to make a STR check against your spell save DC to free itself. Higher Slot: +1d6 damage per slot level above 1.
