The Symbiont (Edit)

Though most warlocks forge pacts with distant, intangible entities, your patron is a physical being of incomprehensible power—a being which dwells inside your very body. This arrangement was struck in the spirit of symbiosis: your patron, which resembles a muscular, living ichor, requires a mortal dwelling, and you in turn may profit from its magic. You can even draw your patron out from where it resides in your blood, causing it to seep forth onto your skin, until you are a monstrous hybrid of ichor and man, replete with claws and teeth to rend your foes asunder.

Symbiotic Transformation

Starting when you choose this patron at 1st level, you can draw out your Symbiont, which proceeds to coat your body in a living slime exoskeleton. You can undergo this transformation or reverse it as a bonus action on your turn. While transformed, you can’t cast spells, but transforming doesn’t break your concentration or prevent you from taking actions that are part of a spell that you’ve already cast. While transformed, you gain the following benefits:
  -The Flesh. Your Armor Class equals 10 + your Dexterity modifier + your Charisma modifier.
  -The Claws. You sprout a set of wicked claws, which you can use as natural melee weapons to make claw attacks. You have proficiency in your claw attacks and can use your Charisma modifier, instead of Strength, for their attack and damage rolls. On a hit, your claws deal 1d8 slashing damage which counts as magical for the purpose of overcoming resistance and immunity to nonmagical attacks and damage. If you later gain the Pact of the Blade feature, your claws count as pact weapons for warlock class features.
  -Extra Attack. Starting at 5th level, you can attack twice with your claws, instead of once, whenever you take the Attack action on your turn. 

The Flesh

Traumatic Rend

Starting at 6th level, you can rake your foe’s eyes with your claws to discourage its attacks. When you hit a creature with your claws twice on your turn, you can make an additional attack using your claws against the target. On a hit, the target has disadvantage on attack rolls against you until the start of your turn. Once you use this feature, you can’t use it again until you finish a short or long rest.

Life Drain

By 10th level, your parasitic patron can draw life from those around you. While you are conscious, whenever you deal damage to a hostile creature using your claws, you regain 1d4 hit points.

Violence After Death

Beginning at 14th level, if you should fall in combat, your Symbiont shall keep fighting. If you drop to 0 hit points while transformed with your Symbiotic Transformation, you do not fall prone or begin making death saving throws until the end of your next turn. Instead, your Symbiont controls your actions, acting as if you were not unconscious, and attacking any hostile creatures it sees. If you take any damage while at 0 hit points, you instantly fall unconscious and suffer one death saving throw failure. At the end of your next turn, you collapse and begin to make death saving throws as normal. 26
