Part of your body has been replaced by plant matter enabling you to morph it at will.

Use your bonus action to morph your plant arm into any desired shape limited to 3 cubic ft. of material. Object created this way can scale to be as flexible as a leaf or as sturdy as a log of wood.

Use your action to morph your plant like arm into a vine-like whip covered in thorns that lashes out at your command toward a creature in range. Make a melee attack against the target. If the attack hits, the creature takes 1d6 piercing damage, and if the creature is Large or smaller, you pull the creature up to 10 feet closer to you.
