Lock away tools and silverware during Meltan infestations, as they can squeeze through the smallest holes. The hex nut can’t change shape, so it’s often left behind. If you find the nut, put it in a wooden bowl and Meltan will get stuck retrieving it. Make sure not to put too many Meltan in the same bowl.

Historians are unsure why Mysterious Boxes appeared recently, nor why Melmetal was sealed after being so revered 3,000 years ago. Maybe Melmetal was the prototype for the Legendary Titans, or it destroyed the Relic Castle, or maybe it helped build the ultimate weapon.
