You return a dead creature you touch to life, provided that it has been dead for longer than a day, but not longer than 10 days. If the creature's soul is both willing and at liberty to rejoin the body, the creature returns to life with 1 hit point but remains unconscious. After the creature's revival, they cannot be healed by any means for 24 hours. If an attempt to heal the creature is made, they will instead take damage equal to the healing they would have received. After 24 hours have passed, the creature will regain consciousness and can be healed normally again.

This spell neutralizes any mundane poisons and cures all nonmagical diseases that affected the creature at the time it died but cannot remove magical diseases, curses, or similar effects; if these aren't first removed prior to casting the spell, they take effect when the creature returns to life. 

This spell closes all mortal wounds, but it doesn't restore missing body parts. The spell can return an undead creature to life, but if the creature is lacking body parts or organs integral to its survival--its heart, for instance--the spell automatically fails. If a body part is removed from the body, but still recoverable, the spell can reattach and restore that body part. for example, if a person was killed by decapitation the spell could reattach their head and restore them to life.

Coming back from the dead after so long is an ordeal. The target takes a −4 penalty to all attack rolls, saving throws, and ability checks. Every time the target finishes a long rest, the penalty is reduced by 1 until it disappears.

While the original version of this spell requires the aid of a divine being, such as a god, this version does not; that is why a sacrifice is required to perform this spell. Since no divine being is called upon to find and return the soul of the deceased individual, the wizard must find the soul themself by following its path through the afterlife. The wizard casting this spell must envelop the sacrifice's soul in magical energy and project it through the target's remains. By doing this, the sacrifice's soul will carry the caster's mind along the same ethereal pathway that the target's soul took. Once the caster finds the target's soul, they must shroud it in necromantic power and have it latch onto their magical energy. Then, the caster can release the sacrifice's soul. Without the sacrifice's soul tethering the caster's magical energy, it will snap back to their body, taking the target's soul that has latched onto that power with it. The shroud of necromantic energy allows the target's soul to pass through the veil of death and into the world of life with ease, as well as is what restores the target's body. It takes a while to dissipate, causing the newly revived target to remain unconscious and unable to be healed for a day after their body's restoration.

At Higher Levels. When you cast this spell using a spell slot of 7th level or higher, the time after the revival of the creature where it remains unconscious and unable to be healed is reduced by 8 hours for each slot level above 6th.
