Stellar Knife throwing animation. Note how the knives only home in after coming to a complete stop.

The Stellar Knife is a Hardmode dagger dropped by Aries after Astrum Aureus is defeated. When thrown, it moves and rapidly spins in the direction it was initially thrown, slowly decelerating and losing spin speed over time. Once the knife fully decelerates, it then remains still until an enemy is within its detection range for it to home in.

Performing a stealth strike with the Stellar Knife causes ten knives to be thrown instead of one. If more than fifteen knives are present, this effect cannot trigger.

Its best modifier is Flawless.


  • Stellar Knives may also be obtained from Astral Crates after Astrum Aureus is defeated.


  • The tooltip is a reference to the third story arc of JoJo's Bizarre Adventure, Stardust Crusaders. In it, The World ("Za Warudo" as pronounced in Japanese) is the Stand of Dio Brando / DIO, which allows him to stop time.
    • The way the weapon works references to how DIO often uses his knives in stopped time, stopping along with the time before accelerating once the time resumes.
