Vine Grapple

Two vines burst out of the ground and wrap around the targets wrists. The targeted creature may make a saving throw, DC equal to your spell save DC. On a success, nothing happens. On a failure the creature is grappled by the vines. The vines can be escaped with a strengh check, Dc equa; to your spell save DC. Escaping the vines takes a bonus action. An ally can also assist by attacking the vines, which have health equal to your spellcasting ability (both vines are treated as one monster).

For each level this spell is increased to increase the lenght of the spell by one round. If this spell is cast at level 2 or higher, the vines grow thorns, dealing 1d4 damage per spell level (so 3d4 if casted at level 3).
