Vampiric

You are a creature of shadow and blood, for your innate magic comes from the deadly vampire. You might trace your lineage from an ancestor whose blood was tainted with a vampire. Possibly you were a part of a dark ceremony against your will that changed you, or perhaps you were bitten by a vampire and survived the transformation but its effects transformed your being.
The power of vampiric magic casts a strange pall over your physical presence. The spark of life that sustains you is muffled by a naturally dark desire, as if it struggles against the predatory magic that imbues your soul.
At your option, you can pick from or roll on the Vampiric Sorcerer Quirks table to create a quirk for your character.

Vampiric Sorcerer Quirks:

This ability has no effect on undead or constructs. You can use this ability a number of times equal to your proficiency bonus. You gain all expended uses after a long rest.

You cannot be frightened or charmed. You become Immune to necrotic damage.
For every 10 years that pass, your body only ages 1 year.

When you attack a creature with your Blood of Thy Enemy feature, add your charisma modifier to the total damage.
Creatures that are charmed or frightened by you are inflicted with double damage.
If a small or medium creature drops to 0 hit points from your Blood of Thy Enemy feature, you can spend a sorcery point as a bonus action and animate it, causing it to stand up immediately . The creature uses the zombie stat block in the Monster Manual.
In combat, the zombie's turn comes immediately after yours. It obeys your mental commands and the only action it can take is the Attack action, making one melee attack.
It remains animate for 1 hour, after which time it collapses and dies.
