God Killer

The God Killer is a Hardmode magic gun that can be bought from the Tracker after completing the "Destroy All Monsters" contract. It fires an atomic ray that has a very long range, pierces infinitely, and briefly inflicts Granite Surge on hit. The ray will be fired continuously until the attack key is released or the player runs out of mana.

Because the God Killer has no knockback, it cannot have any modifiers that affect knockback, including Mythical and Ruthless. Therefore its best modifier is Demonic for damage output, or Mystic for mana conservation.

Trivia

 * The design and name of the weapon, alongside its atomic-based attack and availability after defeating a Mothron for the Tracker, are a reference to the monster.
