List of items in Once Upon a Time
When Mr. Gold attempts killing Zelena, her life-force was freed after the fatal blow; it fled back to her pendant, releasing her magic and completing the time travel spell. It appears that if this is done, the Pendant's wearer regains back all their magic, since Zelena was able to regenerate her body and kill Marian, before "taking her place" with a glamour spell, within the short time that Hook and Emma were distracted. During the episode "Mother", Regina even states she put the magic-canceling bracelet on Zelena to prevent spell-casting. Zelena even implies that her magic is back. In "The Dark Swan" Zelena proves this, by cutting off her hand to remove the magic-canceling bracelet, and magically reattaches her hand.
