The Atom Splitter is a post-Moon Lord javelin that is dropped by the Exo Mechs after XS-01 Artemis and XS-03 Apollo have been defeated last. When used, it throws out a gravity-defying javelin that travels through tiles and emits light. Upon contact with an enemy, 15 rainbow javelins randomly appear from all sides of the target, each dealing 70% damage and pierces twice but have a very short lifespan.

Performing a stealth strike with The Atom Splitter will cause the resulting javelin to spawn 100 rainbow javelins that deal 23% damage each.

Its best modifier is Flawless.



  • The item's name refers to how, in real life, the act of splitting an atom has the potential to release excessive amounts of heat, or even create large explosions, which is key to the functionality of nuclear reactors and nuclear bombs.
