Sorcerer: Death's Vigor
Sorcerers are fueled by the innate power of the world. Nothing, however, is more powerful than a human life. And some sorcerers, like you, use this power to thrive. Death fuels you. Grows your strength. Stories tell of how you may have found this power. Individuals who have returned from death and need the energy it provides to survive. Other tales talk of dark necromantic rituals which imbue an individual with these abilities. Perhaps you were just a child of a vampire.
Sorcerers fueled by Death's Vigor rarely deal with positive stories. At the worst end, people talk of liches, seriel killers, or brutal assassins. At best they are murder investigators, personal guards, or feared soldiers.
Death's Aquaintence
1st-level Necrotic Vigor feature
Your familiarity with death and the circumstances surrounding it allows you a greater breadth of knowledge. You gain proficiency in either Insight, Investigation, or Survival. You have advantage on skill checks to determine cause of death or determine how deadly something is.
By spending 1 minute with a corpse you may magically hear its last words. At 3rd level you may briefly see its last moments. You may do this a number of times equal to your proficiency bonus and regain all uses on a long rest.
Death's Stasis
1st-level Necrotic Vigor feature
You know how to hold creatures from death or health. As a reaction to a creature taking damage or dying you can magically hold that's creature's state. A non-dead target must make a Wisdom Saving throw, although it may choose to fail.
The held target is immune to damage and healing of your choice, however it cannot take any actions or reactions and may not benefit from any bonus to its speed. The creature to most recently deal damage to the target at 0 hit points is considered the one to have killed the target. This effect ends at the end of your turn or when you dismiss it as a free action.
You may use this ability a number of times equal to your proficiency bonus and regain all uses on a long rest.
Grim Harvest
6th-level Necrotic Vigor feature
You gain the ability to reap life energy from creatures you kill with your spells. Once per turn when you kill one or more creatures with a spell of 1st level or higher, you regain hit points equal to twice the spell's level, or three times its level if the spell deals necrotic damage. You don't gain this benefit for killing constructs or undead.
Restoritive Death
6th-level Necrotic Vigor feature
Your magic stays constant as you absorb the power of death. If you use a Metamagic option on a spell and that spell kills a creature, you regain all the Sorcery Points spent on that spell.
Improved Restoritive Death
14th-level Necrotic Vigor feature
Magic returns to you when you use it to kill. When you kill a creature using a spell of 1st level or higher, you immediately regain that spell slot back. If the spell slot spent is over 5th level, you may regain a spent spell slot of 5th level or lower.
Necrotic Explosion
18th-level Necrotic Vigor feature
When a creature you kill dies it explodes, possibly creating more death to those around. When you kill a creature you may use your reaction to force the corpse to release a up to 6 shots at nearby creatures. Make a ranged spell attack for each shot, dealing 3d8 necrotic damage upon each hit. If another creature is killed from this attack, you repeat this process again. You are healed 1d8 for each creature you hit this way.
