Like the Ring of Sacrifice, upon death, the wearer will retain any souls and humanity that they were carrying with them (as well as retaining unhollowed form), but the ring itself will shatter. Furthermore, if the player would have been Cursed upon death, they are instead not cursed. However, if the player was already cursed before they died, the curse will not be lifted. Dying with a Rare Ring of Sacrifice equipped will show the message "Rare Ring Revival" after the usual "You Died" message and will not result in the player leaving a bloodstain. Should a player with an uncollected bloodstain die while having a Rare Ring of Sacrifice equipped, their bloodstain will not be lost.
Like the Ring of Sacrifice, the Rare Ring of Sacrifice acts as an extra life, of sorts. It can be useful to the player if they are taking on a tough enemy (especially one that can inflict a curse upon them) for the first time or making a difficult jump that may result in death. Because the player will not leave a bloodstain upon death with this ring, it can make traversing a difficult area less risky. Because of its rarity, however, using a regular Ring of Sacrifice will be more useful in cases where a risk of being cursed is not present.
