Twofold Soul

You touch two creatures, one living and one dead. If the dead creature has been deceased for longer than 24 hours, or if either creature is undead, the spell fails. If the dead creature's body is not whole, a part or piece of the creature, such as a bone or lock of hair, will suffice. If both creatures are willing, you bind their souls together, reviving the dead creature with 1 hit point.

This spell neutralizes any poisons and cures normal diseases afflicting the creature when it died.

This spell closes all mortal wounds and restores any missing body parts, or creates a new body should the original be damaged or destroyed beyond repair.

Upon resurrection, the two creatures are considered Twin Souls for a period of one year, or until Greater Restoration is cast on both creatures simultaneously. While twinned, the two creatures share a deep bond. The following features apply while twinned creatures are within 60 feet of each other:

• Twinned creatures are able to communicate telepathically with each other.
• When a twinned creature takes damage, the other twinned creature may use their reaction to take half the damage.
• When a twinned creature is healed by means of a spell, they may choose to only heal for half the amount, granting the rest to their twin.

Should either creature die by any means while twinned, the other will instantly die, automatically failing three death saving throws. A creature currently considered a Twin Soul may not participate in another casting of Twofold Soul, but may be resurrected by other means.
