Each Silver Sphere in Nokstella will always drop a Larval Tear upon defeat, but only once. Unlike Silver Tears, Silver Spheres are not weak to Lightning damage. Oddly enough, the Silver Sphere in Nokstella hanging from the ceiling from which many Silver Tears drop is hostile to those Silver Tears, and will kill them all if the player keeps their distance. The large metal rolling balls that are summoned out of nowhere in CaelidRegion use the same model as the Silver Spheres, and disintegrate upon missing the player or encountering an obstacle. They also do not drop Larval Tears. They are included on this page because they are visually indistinguishable, even though their function and behavior in the game is quite different. Unlike the ones in CaelidRegion, the metal ball trap in Raya Lucaria AcademyDungeon is not a Silver Sphere at all, and is instead completely smooth. It also continuously respawns until the player kills the Glintstone Sorcerers upstairs that are summoning it; again unlike the ones in CaelidRegion, which do not actually respawn until the player rests at a Site of Grace. Despite their size, is very easy to block with a shield. Terrain such as the sides of stairs or the edge of a pillar can easily block its ramming attacks while allowing you to attack them from safety.
