Hexblood

Whether by entering a pact with an entity yourself, or you were promised by your parents before birth. Your very lifeblood belongs to a higher power. Often mistaken for a sorcerer, your power is in your blood, bestowed upon you by a pact with a higher power.

Living Weapon

Your magic being internal has made you strong on your own, an empty handed, unarmored, living weapon for your patron. When you are not wearing armor, add your CHA modifier to your AC (not stacking with fixed value natural armors, such as the Tortle's)

You gain the "unarmed" fighting style from the fighter's list. Using instead your CHA modifier for attack and damage rolls.

If unarmored and unarmed, add your CHA modifier to your Initiative rolls.

As you level up and take Eldritch Invocations, ones that can be applied to an eldritch blast can also be applied to your unarmed strikes. If you select Pact of the Blade it is for you "Pact of the Fist" and invocations that would apply to a weapon apply instead to your unarmed strikes.

Bloody Oath

After you first take damage from a foe in combat, for one minute you can dodge, disengage, dash, or make one unarmed strike as a bonus action.

Additionally, your Patron imbues your unarmed attacks with preservative magic, and you gain multiattack.

When you kill a foe with an unarmed strike while this feature is active you gain THP equal to your CHA modifier (double this number if the creature you killed is the one who triggered this feature)

 

At level 10 your strikes become reinforced with the growing strength of your pact. While your blood oath is active, you may add your proficiency bonus to your unarmed strikes damage rolls.

At level 14 you have mastered the art of unarmed combat. When your Bloody Oath feature is active, you may make three unarmed strikes when you take the attack action. Your unarmed strikes now do force damage and improve to 1d8 damage or 1d10 if you are unarmored and unarmed as your patron's very essence reinforces your blows.

 

Sacrificial Healing

Over one minute, you formulate a healing tonic out of your blood for an ally:

expend one hit die, healing your ally for twice the total, and you take damage equal to half the total rounded down.

 

Eldritch Fortitude

You gain proficiency in Constitution saving throws

You gain resistance to Necrotic damage.

When rolling hit die (including for your Sacrificial Healing feature), treat your CON modifier as +5
