You Curse a target's Soul, and they begin to deteriorate.
You deal Necrotic damage per Round, per Gift used, to the Target for as long as you maintain the Curse.
If they die, you gain 1 extra year of life in your prime, or de-age to your prime if you are older than your prime.
You see the target's skin paling, veins darkening as the Curse takes hold. Each second, their vitality drains away, leaving a gaunt, withered figure. Necrotic energy pulses from your hand, binding their soul to your will.
