Cormack's Primordial Incarnation

You channel the magic of the primordial, transforming yourself into an incarnation of an insurmountable force of nature, which lasts until the spell ends. When you cast this spell, you choose one of the following incarnations: Verdant Land, Tempestuous Seas, or Squalling Skies.

Verdant Land. Your limbs become those of an ancient tree, your feet become rooted in the ground beneath you, and around you the air becomes thick with pollen and clouds of insects. While transformed in this way, you gain the following benefits:
- Each time you hit a creature with a melee attack, the target suffers an additional 1d12 force damage, and it must succeed on a Strength saving throw or be pushed 10 feet away from you
- You emanate an aura which extends 20 feet from you in every direction, but not through total cover. The first time a creature enters this aura or starts its turn there, you may choose for it to gain 5 temporary hit points or suffer 5 points of poison damage.
- As long as you are stood on solid ground, you cannot be knocked prone.

Tempestuous Seas. You grow four tentacular limbs, your demeanour becomes as capricious as the changing tides, and the force of eerie tides draws your enemies towards you. While transformed in this way, you gain the following benefits:
- Each time you hit a creature with melee attack, the target suffers an additional 1d12 force damage, it must succeed on a Strength or Dexterity saving throw (their choice) or become grappled by you.
- You emanate an aura which extends 20 feet from you in every direction, but not through total cover. Each time a creature starts its turn within the aura, you may force it to make a Strength saving throw or be moved 10 feet towards you.
- As long as you are stood or submerged in water, you cannot be charmed.

Squalling Skies. Your strikes are infused with the power of elemental air, you move with the unstoppable momentum of a storm, and the air around you churns with powerful winds. While transformed in this way, you gain the following benefits:
- Your reach increases by 10 feet, and each time you hit a creature with a melee attack, the target suffers an additional 1d12 force damage.
- You emanate an aura which extends 20 feet from you in every direction, but not through total cover. Ranged weapon attacks targeting objects and creatures within this area are made with disadvantage.
- As long as you do not stand on solid ground, you cannot be restrained.

Immediately after the spell ends, you must succeed on a DC15 Constitution saving throw or suffer one level of exhaustion.
