Stardust armor

Stardust armor is a post-Moon Lord set of armor that provides summon weapon boosts. It is currently the final summoner set available on the. Crafting the full set requires a total of 36 Luminite Bars (144 Luminite) and 45 Stardust Fragments. Wearing the full set increases the wearer's minion capacity by 5 (to a total of 6), along with granting +66% minion damage.

Equipping a full set of Stardust armor causes a unique Stardust Guardian minion to follow the wearer. It is passive until a Hostile Enemy is within a 30 block radius to the player, causing it to quickly move through even blocks to the enemy, which then strikes it rapidly with Small Fist shaped blasts, after there are no hostile entities within range, the Stardust guardian will return to following the player passively. The Stardust Guardian does not count against the player's minion capacity.

Tips

 * Using Stardust armor and accessories and buffs, it is possible to have 11 minions, not counting the Stardust Guardian.
 * While it is a potent offensive set, Stardust armor has relatively low defense, and while its ability to attack any enemies that come within a far distance of the player compensates somewhat, the stardust guardian does not protect the user against projectiles which leaves them vulnerable. The Valhalla Knight's Breastplate can be substituted into the set to provide much greater survivability, sacrificing the Guardian, and two minion slots.
 * The Guardian can move through blocks to attack a hostile mob whether or not has targeted the player. This can be exploited by walling yourself in, allowing the Guardian to take care of enemies.

Trivia

 * The Stardust Guardian appears to be a reference to Algalon the Observer from the massively multiplayer online role-playing game . This was probably a joke.
