Not to be confused with Anahita, the boss that is summoned when it dies.

??? is a Pre-Hardmode stationary enemy that spawns in the Ocean. When it is killed, it summons Anahita. In Revengeance Mode, it can drop the powerful Aquatic Heart accessory at any point in the game. It can also be detected by the Lifeform Analyzer.


  • Due to its ability to spawn in Pre-Hardmode, it is possible to kill it and summon the powerful boss(es) by accident. However, this is not recommended as this boss can easily one-hit the player in Pre-Hardmode with its massive damage.
  • It spawns 4x as often in Hardmode.
    • After defeating Calamitas or Plantera, its spawn rate is additionally boosted by 4x, totaling 16x.
  • It cannot spawn in the Sulphurous Sea biome.


  • When ??? is nearby, the song Siren's Call, which was composed by the artist DM DOKURO, will play unless the Calamity Music add-on mod is disabled.
