Blood War Sorcerer

Tbe Blood War Sorcerer Focuses on using its own hp as a resource 

Strength in Blood

Reverberations from the Blood War ripple through the realms and resonate within you, granting you control over the essence within your body to ready yourself for bloody conflict. As a bonus action, you can expend one Hit Die and roll it, dealing the result as necrotic damage to yourself. This damage cannot be reduced or negated. You pour your burning blood onto a melee weapon you are holding, turning it into your Blood Weapon and allowing you to change its shape into any other melee weapon. Alternatively, if you lack a melee weapon, you may instead pull your blood from your body and manipulate its shape and density into the form of any melee weapon of your choice. You may only have one Blood Weapon at a time.

You are proficient with this Blood Weapon and may use its mastery property. You may use this weapon as a spellcasting focus. When you attack with this weapon, you can use your Charisma modifier, instead of Strength or Dexterity, for the attack. The weapon maintains its shape until you return the blood to your body (no action), the weapon leaves your grasp, or you use another bonus action to change its shape again. If you return the blood to your body, you regain the Hit Points and Hit Die you lost to create the weapon.
