Circle of the Symbiote

While many Druids are expert summoners and shape-changers, Druids of the Symbiote, or Symbiotics, find different ways to harness their bestial abilities. These Druids use a process called spirit channeling to empower their own bodies with the powers of animals, and allow them to create a sychronized hybrid of nature and Druid.

Symbiotics see the world as it stands today differently than other Druid Circles. They wish to find a way to combine the efficiency and inventiveness of sentient races with the raw power and ancient knowledge of nature, seeing hybridization the best route to survival.

Spirit Channeling

Through deep communication and understanding with bestial spirits, you have gained the ability to coalesce your two forms into one, more powerful, being. Starting at 2nd level, as a bonus action, you can expend a use of your Wild Shape feature to channel a spirit, using your body as a host. You gain temporary hitpoints equal to your druid level multiplied by the two-thirds of the max result of your chosen beast's hit dice, rounded up. Your strength score becomes equal to the beast's strength score, and you gain any speeds the beast had. Additionally, if the beast you channel can breathe in water or have the Hold Breath ability, you gain it as well. You can channel a beast with a challenge rating as high as 1. These benefits last for an hour, until you lose all these temporary hit points, or until you use your Wild Shape again.

Starting at 6th level, you can transform into a beast with a challenge rating as high as your druid level divided by 3, rounded down.

Empowered Spirit Channeling

At the 6th level, you now hold deeper connections with the spirits that you channel. When spirit channeling, if the beast has the multiattack feature, you can make two attacks rather than one when you make the attack action.

Cleansing Spirits

At 10th level, the spirits you summon tend to your wounds as they enter the mortal plane. When you Spirit Channel, you regain a number of hitpoints equal to your druid level, and you can choose to remove one condition afflicting you. The condition can be Blinded, Charmed, Deafened, Frightened, or Poisoned.

Pack Channeling

At 14th level, your ability to summon spirits increases. When you use your Spirit Channelling feature, you can simaltaneously cast the spell Spirit Guardians at the 3rd level, without using a spell slot. The spirits summoned appear as beasts of the same type that you channeled.
