    - Effect: On hit, target makes STR saving throw (DC equals your spell save DC) or is restrained until your next turn.

  - Self: Your body transforms into a mass of living vegetation, with bark-like skin and leaves sprouting from your limbs as thorns erupt from your fingertips like claws, dripping with poison.

    - Effect: Your unarmed strikes deal 1d6 poison damage, and you regain hit points equal to the poison damage dealt on contact.

Air:

Storm
