Methuselah

Grave Empathy

The undead can innately sense your closeness to their kind. Whenever an undead tries to attack you, it must make a Wisdom saving throw. On a failed save, its attack misses. On a successful save, the undead is immune to this feature for the next 24 hours.

Corpse Shepherd

You can perform a 10-minute ritual to summon a Medium humanoid corpse or pile of bones (your choice), which is magically teleported to your location from a random cemetery.

Spellcasting: Dead Alive

While bound to Methuselah, you can raise corpses at your touch. You can cast the following spells, without expending a spell slot or material components: At will: false life 3/day: animate dead 1/day: create undead You regain all expended uses of these spells when you finish a long rest.

Trait: Venerable

While bound to Methuselah, you appear dramatically aged. Your voice descends into a hoarse rasp, your hair grows white, and deep wrinkles appear in your skin. Additionally, you can siphon the life and youth from others. As an action, you can make a melee spell attack against a hostile creature you touch. On a hit, the target takes 4d6 necrotic damage, and you regain hit points equal to half the necrotic damage dealt

A man who grew so old that he slipped between life and unlife, Methuselah grants his binders authority over undeath and his strange disconnect from mortality.

Legend

Methuselah was a man so loved by the gods that they blessed him with unnaturally long life —so long, in fact, that he became the oldest mortal to have ever lived.
Methuselah spent his first century of life raising a family. But when he outlived his children and his grandchildren, Methuselah was heartbroken. He went to live with the elves, but in time he outlived generations of them too. In his most venerable age, his bones became brittle, his teeth fell out, and his skin wrinkled and lost its color. When at last Methuselah lay on his deathbed, he was little more than a husk, cursing the gods for their so-called blessing and pleading for the release of death.
Today, Methuselah is venerated by necromancers and intelligent undead as the Eldest, the wisest and most venerable among the deceased. Their reverence paints him with a kind of undeath, as demonstrated by his vestige: a shambling corpse missing its eyes, teeth, and nose, with wispy white hair and a beard that hangs to the floor.

Personality Trait

While bound to this vestige, you gain the following personality trait: “I believe myself to be far older, wiser, and wearier than  others.”
