Mechanical Determination. If damage reduces the wonder to 0 Hit Points, it makes a Constitution saving throw with a DC of 5 plus the damage taken unless the damage is Lightning or from a Critical Hit. On a successful save, the wonder drops to 1 Hit Point instead.

Wind-Up Operation. The wonder has the Unconscious condition until another creature winds it with the wonder's unique key for 1 minute. Once wound, the wonder operates for 10 days or until a creature touches the wonder with its key as a Utilize action to deactivate it, after which the wonder has the Unconscious condition until it is wound again.
