|Exo Mechs (Artemis and Apollo)||1||50% / 66.67%|
The Atom Splitter is a post-Moon Lord javelin that drops from the Exo Mechs after XS-01 Artemis and XS-03 Apollo have been defeated last. 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 with 14.4% 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.
