When this is extracted and refined, it apparently protects skeletons from Spinjitzu, which is the only method of defeating them. Maelstrom ore leads in pipelines that run from the drills in the center of the quarry, which then liquifies the ore. This can be seen in the ore meters that are around the Maelstrom Quarry.
It can be noted that if many skeletons are mining, the meter rises. Once a player begins to smash them, the meter lowers once again.
