With a howl like the damned, several bolts of black lightning leap from your target to you. You drain away its life force and use it to power your own magic. The target must make a Constitution saving throw. The target takes 20d8 necrotic damage on a failed save, or half as much damage on a successful one. In addition, its hit point maximum is reduced by the amount of damage it takes. After a long rest, the target's hit point maximum returns to normal. For every 20 points of necrotic damage you inflict, you regenerate a 1st-level spell slot. You can combine spell slots to regenerate higher level spells. For example, if you do 85 points of damage, you could regenerate one 4th-level spell slot, four 1st- level spell slots, or any combination that does not exceed 4 spell levels.
