Stardust armor

Stardust Armor is a Hardmode armor set that is crafted using Stardust Fragments and Luminite Bars. This set increases the max minion count and the damage that the minion does, making it ideal for summoning minions and weapons. A full set summons a Stardust Guardian which follows the player around. The Guardian can be placed as a stationary minion by double tapping down and pointing to a location. When hit with the Stardust Guardian's explosion, enemies target the Guardian instead. It cannot be placed midair much like the Staff of the Frost Hydra. You may return the Guardian to yourself by holding down. The Guardian is dyed by the pet slot.

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

Tips

 * The Stardust Guardian does not count towards the player's total minions. All in all it is possible to have 11 minions plus the Guardian.

Trivia
