Symbiotic Refugee

once a mighty race, the symbiotic ooze are now on the run as their home has been destroyed by several Astral Dreadnoughts. Symbiotes are willing to give anything to find a new home and a way of survival. Often these deals provide the symbiote with a willing host who vows to protect them above all else, including their own life, for access to their profound abilities that they developed from within the astral plane.

• You gain temporary health equal to 1d12 + Warlock level 

• Upon transformation / Crit - any enemy that can see you within 60ft must make a WIS saving throw or be frightened of you for 1 round
  • If you kill a frightened enemy you regain health equal to half the damage dealt on the killing blow

Symbiotic Attunement

Symbiotic Synergy

You no longer need to breathe, eat, or drink as your astral plane patron starts to fuse with you on a molecular level. You are considered "ageless" as your body continues to connect with the astral plane, and you no longer age when being a host to your symbiote. In addition all direct damage output done by the host is changed to necrotic damage, also once per turn you can add one additional damage dice to a melee attack. 

Symbiotic Survival

As a last resort, when you reach 0 hit points your symbiotic patron explodes itself in a giant 30 ft sphere causing necrotic damage equal to 1d10+ Warlock level. You are then revived with 1 hit point per warlock level and gain one level of exhaustion. You cant do this again until a long rest

Symbiotic Fusion

Now that your patron and you have fully fused and bonded together you can use your bonus action to regain hit points equal to 1d10+ Warlock level.  Additionally you can reattach a severed limb while using this ability. This action can be used once per long rest.
