This silvery silk wristband has patterns of the moon adorning it. 

Curse. This wristband is cursed, a fact that any amount of moderate inspection reveals. The wristband is bound to a creature's life. For each day past the first two that you are attuned to this wristband that the creature lives, your hit points are reduced by 5, and your hit point maximum also decreases by 5. If your hit points are reduced in this way seven or more times, you become unable to use the hand which the wristband is tied to. When the creature dies, the wristband falls off of your wrist, and a dragon of royalty can also destroy the band as an action. The wristband is otherwise indestructible.
