Aureophage (Calamity's Vanities).gif

The Astral Infected Icosahedron is an Expert Mode-exclusive pet summoning item obtained from the Treasure Bag dropped by Astrum Aureus. It summons an Aureus themed version of the Astrophage to follow the player.


  • The pet was originally named "Astrophage", but was changed to "Aureophage" after the Calamity mod added an Astrophage pet.
  • The tool tip “Roll for initiative!“ refers to how table top roll playing games take turns during combat, the phrase is most commonly associated to the RPG Dungeons and Dragons.
  • The pet closely resembles a “bacteriophage“ a virus that infects forms of bacteria. Its name “Aureophage” also resembles the name of the “bacteriophage”.
