The Guardian can be placed as a stationary minion by double tapping down and pointing to a location. It cannot be placed midair much like the Staff of the Frost Hydra.

Crafting this set requires a total of 36 Luminite Bars (144 Luminite) and 45 Stardust Fragments.

Trivia

 * The Stardust Armor item set is most likely a reference to Stardust Crusaders, the third adaptation of a popular japanese manga series named Jojo's Bizarre Adventure. The series features spectral manifestations of a persons battle spirit, referred to as having a Stand, by which the main characters do battle. The stand can be controlled and summoned at any moment by the user much like this armor allows the wearer to project a "stand" of its own.
