Hyper-Threader

The Hyper-Threader is a item in Risk of Rain that causes every attack to fire a laser that bounces to two enemies.

Trivia
The Hyper-Threader, using "directed energy", may be a reference to Halo's Type-25 Directed Energy Rifle, more commonly known as the Plasma Rifle, looking slightly similar in appearance.
