True Resurrection

You bring back to life a creature that has been dead for no longer than 200 years and that died for any reason except old age.

If the creature's soul is free and willing, the creature is restored to life with all its Hit Points.

This spell closes all wounds, neutralizes any poison, cures all Diseases, and lifts any curses affecting the creature when it died. The spell replaces damaged or missing organs or limbs. If the creature was Undead, it is restored to its non-Undead form.

The spell can even provide a new body if the original no longer exists, in which case you must speak the creature's name. The creature then appears in an unoccupied space you choose within 4m of you.

Variant Resurrection Rules. In order for this spell to work, a resurrection ritual must be performed as part of the casting time of the spell. Up to 3 allies can make a contribution to the ritual, which usually signifies some kind of relationship they have had with the person, as they beseech the soul back to the land of the living. The DM determines what kind of ability check needs to be made, along with the DC, based on the contribution.

Then, the DM makes a resurrection check, rolling a d20. The DC starts at 10 + the number of times the target has been brought back to life. Then, the DC is increased by 1 for each ritual contribution that failed, and it is reduced by 2 for each contribution that succeeded. On a successful check, the resurrection ability is successful, but on a failed check, the resurrection ability is unsuccessful, and the creature can no longer be brought back to life.
