Circle of Thorns

A circular hedge of thorns rises in a 5-foot cube you can see within range. If a creature is inside the cube, it must make a Dexterity saving throw or take 1d6 piercing damage and be restrained until the start of its next turn. To move through or exit the cube, a creature may attempt to make a Strength or Dexterity (target's choice) check, but doing so also causes them to take 1d6 piercing damage. The thorns wither away at the start of your next turn. 

      This spell's damage increases by 1d6 when you reach 5th level (2d6), 11 level (3d6), and 17th level (4d6).
