Blood Warrior

Your max HP increases by 1 for each level in this class and you instead use a d8 hit die rather than d6

Parasitic Bond

You create a parasitic bond with a target, if the target is not willing the DC is 10+1/2 your level in this class+1/2 Spell attack modifier con saving throw. the Target makes the saving throw with advantage if theyre at full hp

You have advantage on attacks against the target, you know the general direction of the creature as long as it is in the same plane as you, and you may leech 1d6+1/2 blood sorcerer level in HP from the target adding it to your own once per round, this does not cost any actions and happens at either the end or beginning of your turn. Only one parasitic bond may be active at any time

This damage evolves to 2d6 @ level 5, 3d6 @ level 10, 4d6 @15, 5d6 @20 

Blooded Exchange

Starting at 6th level, if you would spend sorcery points and you have less than half your maximum sorcery points left, you may spend your hit points instead. You spend 15 hit points per sorcery point

pool of blood

At 14th level, you may transform into a pool of blood that occupies the same space you did. Your movement decreases by 10.  You may now occupy the space of another, when you do you may have them roll a charisma saving throw or they take 5d4 necrotic damage and their movement is cut in half on a fail, half damage if they succeed and their speed remains normal. You then regain hit points equal to half the damage dealt.

Sanguine master

You can have three parasitic bonds at a time. As a bonus action if any target is damage you may distribute up to 1/2 of the damage among the other three in the Bond. Additionally when you choose to life drain a target you max the first damage die. 

You now gain an additional sorcerer point whenever you convert your life for metamagic.
