Chaotic Ore is a Hardmode ore which generates in the Abyss biome. It can be found on the underside of the floating Abyss Gravel islands, dropping harmful lava particles into the water beneath itself. These lava particles have a base damage of 25.
It requires at least a Picksaw to mine, and is used to craft Chaotic Bars at an Adamantite Forge or a Titanium Forge. It is also dropped by Chaotic Puffers and Devil Fish after the Golem has been defeated.
- Destructive explosives, such as Bombs or Dynamite, can be used to destroy this ore after the Golem has been defeated.
- The lava particles that this ore drops can provide natural light to the normally pitch-black Abyss.
- This ore used to generate in The Underworld, but it was later relocated to the Abyss.
- This was to give further incentive to explore the Abyss, and also because the ore had issues with generating into the Underworld's ruined houses.
