Spirit Recall is a powerful ritual that can sometimes restore life to a deceased person by manipulating time, causing it to reverse itself in an area immediately surrounding the target of this ritual. When the ritual succeeds, the deceased person's body is regressed in time to a point prior to injury, fatal disease, fatal accident, etc. and coaxes the spirit back into its physical shell.
If this ritual is successful, you return a dead creature you touch to life, provided that it has been dead no 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.
This spell also neutralizes any poisons and cures nonmagical diseases that affected the creature at the time it died. This spell doesn't, however, 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. The spell can't return an undead creature to life.
This spell closes all mortal wounds, but it doesn't restore missing body parts. If the creature is lacking body parts or organs integral for its survival--its head, for instance--the spell automatically fails. If cast by someone with 30+ arcane and/or clerical caster levels, even missing body parts are restored as part of the spell or ritual.
Coming back from the dead 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.
When enacted as a spell instead of a ritual, this effect is called Restore Life and casting the spell saps the caster, leaving her with one level of "One D&D"-style exhaustion. This exhaustion doesn't occur if this is enacted as a lengthier ritual.
