Binding Brambles

You choose one target within range, forcing it to make a Strength saving throw. On a failed save, the target is restrained and begins taking 3d6 piercing damage at the beginning of each of its turns, as thorny plants bind their body and restrict their movement. A creature that is currently restrained by this spell can use their action on their turn to make a Strength (Athletics) check against your spell save DC. On a success, the spell ends.

At Higher Levels. When you cast this spell using a spell slot of 4th-level or higher, the number of creatures you can target with this spell increases by 1 for each spell slot level above 3rd.
