The Defective Sphere is a Hardmode rogue boomerang that is dropped by Deadly Spheres. It automatically throws up to five spheres, depending on stack size, with each sphere randomly choosing one of four types:
Sphere Types[edit | edit source]
|A sphere that returns to the player after striking an enemy.|
|A high velocity sphere that moves swiftly and returns to the player after striking an enemy.|
|A extremely high velocity sphere that ignores tiles and pierces indefinitely until returning to the player.|
|A sphere that will home-in on enemies and explode on contact. This sphere will not return to the player.|
Performing a stealth strike with Defective Spheres will cause all sphere types to be thrown at once, regardless of stack size.
The Defective Sphere cannot have modifiers through any usual in-game means, due to its stackable nature.
