Symbiotic Patron

Your pact has bonded you to a living magical entity that fuses with your flesh and spirit. 

Level 3: 3rd Level - Symbiosis

As a magic action, you can expend a Pact Magic spell slot to enter your Symbiotic Form, which lasts for 1 minute or until you end it early as a bonus action, are incapacitated, or drop to 0 hit points. While in this form:

• Spellcasting Limitations. You can’t cast spells, but transforming doesn’t break your Concentration or otherwise interfere with a spell you’ve already cast.
• Symbiotic Bond. When you enter the form you gain Temporary Hit points equal to 5 x the level of the spell slot used.
• Symbiotic Shell. While in this form while not wearing armor, your AC becomes equal to 10 + your Charisma modifier + the level of the spell slot used.
• Symbiotic Agility. You can make an Unarmed Strike as a bonus action, you gain a climb speed equal to your walking speed, and you can climb difficult surfaces, including upside down on ceilings, without needing to make an ability check.
• Symbiotic Strikes.  While in this form, your unarmed strikes deal necrotic damage instead of bludgeoning. Their base damage is 1d6, and increases to 1d8 if the spell slot used was 3rd level or higher, and 1d10 if it was 5th level. You can use your Charisma modifier for their attack and damage rolls.

 

Level 3: 3rd level - Symbiotic Spells

The magic of your patron ensures you always have certain spells ready; when you reach a Warlock level specified in the Symbiotic Spells table, you thereafter always have the listed spells prepared.

Fiend Spells

Warlock Level	Spells
3	Disguise Self, Inflict Wounds, Alter Self, Detect Thoughts
5	Nondetection, Haste
7	Evard's Black Tentacles, Blight
9	Contagion, Dominate Person

Level 6: 6th level - Furious Symbiosis

While in your Symbiotic Form, you can make two unarmed strikes instead of one whenever you take the Attack action on your turn. 

Level 10: 10th level - Living Weapon

Living Weapon
When you enter your Symbiotic Form, you gain additional benefits:

• Barbed Limbs – Your unarmed strikes score a critical hit on a roll of 19–20.

• Chitinous Blades – You gain a +1 bonus to attack and damage rolls made with your unarmed strikes.

• Elastic Reach – Your unarmed strikes have a reach of 10 feet.

 

Level 14: 14th level - Complete Symbiosis

You can now enter your Symbiotic Form as a bonus action instead of a magic action. 

In addition, when you take the Attack action on your turn while transformed, the symbiote can make one additional unarmed strike against a different target within range (no action required).

You can use this special attack a number of times equal to your Charisma modifier (minimum 1), and regain all expended uses after a long rest.
