Dvaleer's Invasive Species

Vines or beast spirits spring from your hand to grow around an enemy's body and cut them with thorns, teeth, or claws. Make a melee spell attack against the target. On a hit, the target takes 1d4 piercing damage and must make a Constitution Saving Throw. On a failure, the target is poisoned for one minute. The target repeats the saving throw at the end of its turn each round. On a success the condition ends.

The spell's damage increases by 1d8 when you reach 5th level (2d4), 11th level (3d4), and 17th level (4d4).
