Resurrected

You have been dead for many years, existing peacefully in the afterlife. One day you are ripped from the afterlife and brought back to your old body.  You have been healed back to normal living conditions. 

 

Dead Man Tell no Tales

Starting at level 1, since you are from a time long ago you are proficient in History and Religion.

Due to your revival, you can cast the Spare the Dying cantrip and gain access to an expanded spell list.  

 

Not Today

Stating at level 6, you add your Charisma modifier to death saving throws (minimum of 1). 

You are now resistant to all necrotic damage and can change the damage type of any spell to necrotic for a sorcery point. 

Death Hanging

Starting at level 14, you gain the ability to see how people will die. You can, as a bonus action, choose a number of people equal to your charisma modifier to cause them to see their own death.  The target must succeed to your spell DC, otherwise become frightened of you, also at the start of each turn they will take 2d10 necrotic damage. 

They can make the save at the end of their subsequent turns. 

Old Man, New Tricks

At 18th level, when you cast a spell that causes damage, you cannot roll lower than half the max amount of damage possible. 

Your existence has become hinged on necrotic magic. The flow has begun to tap into your spell casting. Every time you cast a spell, 1st level or higher, that is Necromancy, you regain 1 sorcery point.
