History

The Amulet of Health comes from the celestial planes and is often given as a gift to pious planeswalkers. Once attuned, the symbol on the front of the amulet changes to whatever god or being that the wearer worships.
It was retrieved by the Yankees in Session 44 after defeating the Mummy Lord within the Teokuital Temple.
