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.
All armors made from Luminite have no sell value (As of 1.4.0.1, Luminite armor pieces have proper prices)
The Stardust guardian will not attack any non-hostile creature or NPC, regardless of player interaction.
The Stardust Guardian can be dyed via the pet slot in the player's equipment tab.
Like all armors made from Luminite, equipping Stardust armor makes the player give off light, in this case white. Unlike all other Luminite sets, equipping just 1 piece of the set gives off the full amount of light.
Moving too far from the Stardust Guardian while its attacking will cause it to return to the player as the enemies are no longer within its range.
The base damage of the Stardust Guardian is about 28-30 and considered as summon damage.
Due to the Stardust armor increasing all summon damage by 66%, including the damage of the Stardust Guardian, its base damage is about 43-47.
The Stardust Guardian attacks a Hostile entity about once every .25 seconds and will attack a target endlessly until the target dies or is out of range.
The total bonuses are composed of the following:
+66% minion damage (+22% from each piece)
+5 minion capacity (+1 from the Helmet, +2 each from the Plate and Leggings)
Stardust armor has the lowest defense of the four Luminite armors.
No blocks will halt a guardians attack on an enemy, and will move freely to the enemy to continue the attack if its within range
Tips
Using Stardust armor and accessories and buffs, it is possible to have 11 minions, not counting the Stardust Guardian.
While it's 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.
