Way of the Symbiote

You can no longer live alone, and have a parasitic nature. 

Symbiotic Nature

You are very vulnerable without a host, when you gain a host and stay with it for 5 days, you take its racial traits as your own. When you acquire a new host for 5 days you lose your old hosts racial traits. When you reach 11th-level adaptation, you can take up to 5 of your old hosts racial trait with you. When you reach 20th-level We are, You can take all your past hosts racial traits with you into your new host.

Without a host you are vulnerable to fire and thunder damage and take 1d12 damage each minute and are unable to fight back.
With a host you take damage and healing equally. (The host can be a player or a NPC. You have full control over a NPC but a player character controls movement unless they are unconscious or gets incapacitated). After reaching 6th-level Symbiotic Cloak,  you will be forced into your Symbiotic Cloak if your host is unconscious or incapacitated. When the host dies you are forced to leave the body.
