Stardust Dragon Staff

The Stardust Dragon Staff is a post-Plantera minion-summon weapon that summons a Stardust Dragon character that attacks enemies. The Stardust Dragon is in constant flight and flies through blocks, attacking enemies by flying through them continuously. It leaves a trail of sparkles that provide periodic bursts of light as it moves.

The Stardust Dragon Staff is unique in that if summoned more than once, multiple Dragons do not spawn &mdash; instead, the first spawned Dragon becomes longer by one segment for each additional summoning, broadening its area of attack and increasing its damage output.

Its best Modifier is Ruthless. The Mythical modifier provides the widest array of stats bonuses, but these primarily affect the initial summon rather than the resulting minion. Minions cannot deal critical hits.

Tips
The Stardust Dragon Staff is extremely useful for farming, as high-level summons of it are capable of killing even the toughest non-boss mobs.

If you are using anything other than a summoner loadout, turning off the stardust dragon buff during boss fights is recommended. The stardust dragon attacks so fast that your own attacks might not even connect.

It also appears that the Stardust dragon becomes more powerful during blood moons.
