Cosmic Dagger in use to kill Abomination.

The Cosmic Dagger is a non-consumable Hardmode throwing weapon that is dropped by Martian Saucers during the Martian Madness event. While used, it holds out the dagger and channels an energy beam that will rapidly home in on nearby enemies. The beam will prioritize enemies that have not been hit yet by the beam.

Like most non-consumable throwing weapons, using this weapon builds up an exhaustion meter that appears below the player. Not using the weapon will make the meter slowly go back down. However, if it becomes completely filled, the user will be inflicted with the Exhaustion debuff, causing all non-consumable throwing weapons to deal massively decreased damage for some time. The meter resets after the debuff ends.


  • If the Show Donator Item Color configuration option is disabled, the Cosmic Dagger will have a rarity of Rarity Level: 8 instead of the standard Rarity level: Donator.


  • The weapon, and the quote "I'm Mary Poppins, y'all" in the tooltip, are a reference to the character Yondu from the movie Guardians of the Galaxy Vol. 2.
