Shredder

The Shredder is a craftable post-Moon Lord gun. The primary fire (left-click) shoots a barrage of fast-moving blue energy bolts which split off in many directions and speeds upon impacting any enemy or tile. The secondary fire (right-click) shoots an equivalent barrage of normal bullets. Both firing modes shoot an identical number of projectiles and have the same firing speed and spread pattern. Each shot has a use time of 3.

The Shredder also has a rare item variant called the Infinity that drops from the Moon Lord.

Trivia

 * While the weapon was originally meant as a reference to the Shredder from Turok 2: Seeds of Evil, the item underwent changes in development and is now mainly a reference to the Shredifier (and the Infinity) from Borderlands 2.
 * Its tooltip is in reference to the processor-intensive effects of the primary attack, causing frame rate drops on many players' devices.
