"A cold and dark energy has materialized in space."
Exodium Cluster is a post-Moon Lord ore that generates in Planetoids after the Moon Lord has been defeated. It requires at least one of the Luminite Pickaxes to mine. It is used to craft several items, including Stratus equipment as well as the four Soul Artifacts, which are accessories that correspond to Lunatic Cultist, Providence, the Profaned Goddess, The Devourer of Gods, and Jungle Dragon, Yharon.
- This ore does not have a Slime counterpart.
- This ore is immune to explosives, even after Moon Lord has been defeated.
- Its name is likely a reference to the exosphere, the most distant layer of a planet's atmosphere which merges with interplanetary space.
- It is one of the few ores that can be also crafted, along with Sea Prisms needing Prism Shards.
