Idomancy Sect

Masters at the manipulation of life energy, school of idomancy wizards bring a new focus to necromancy.

Powerful idomancers have the ability to transfer their life energy to a different body, granting them virtual immortality.

Vampiric Regeneration

At 2nd level, you gain the ability to reap life energy from creatures around you. As a bonus action on your turn, you may attempt to create a spell slot from the life energy of a creature of your choice that you can see within 30 feet of you. This creature must make a charisma saving throw against your spell save dc. On a fail, the creature’s maximum hit points are decreased by your wizard level, and you regenerate one spell slot up to level {scalevalue}. You may use this feature a number of times equal to your intelligence modifier, recharging all of the uses on a long rest.
