Tainted, twisted, semi-spectral vines erupt from the ground and spread out from you to a distance of 10 feet for the duration, remaining centered on you and moving with you. For the duration, the vines turn the ground in the area into difficult terrain for hostile creatures. A hostile creature that enters the area for the first time on a turn or starts its turn there must succeed on a Strength saving throw or be restrained by the vines until the spell ends. A creature restrained by the vines takes 2d6 necrotic damage at the start of each of its turns. A creature, including the creature restrained by the vines, can use its action to make a Strength check against your spell save DC. On a success, the restrained creature is freed.
