Hadron Collider

The Hadron Collider is a craftable, non-consumable Hardmode throwing weapon that can autofire. It throws a knife unaffected by gravity; the knife periodically places an unstable atom as it travels. Should the knife strike an enemy, all the unstable atoms will travel towards the struck enemy, each dealing 50% of the weapon's base damage. If the knife does not successfully deal damage, then the unstable atoms it created will vanish.

Like most non-consumable throwing weapons, using this weapon builds up an exhaustion meter that appears below the player. Not using the weapon will make the meter slowly go back down. However, if it becomes completely filled, the user will be inflicted with the Exhaustion debuff, causing all non-consumable throwing weapons to deal massively decreased damage for some time. The meter resets after the debuff ends.
