Light Disc

The Light Disc is a Hardmode boomerang-type weapon that deals Melee damage. Up to a total of five Light Discs can be crafted and stacked in a single slot, which allows them to be thrown in succession, with multiple discs in the air at once. Repeated throws can occur automatically while the attack button is held. Light Discs are quicker than other Boomerangs, and can ricochet up to four times.

Light Disc physics are similar to the Thorn Chakram, though they have nearly twice the range and don't "wobble" as they travel. They also emit a small amount of light, comparable to the glow of Demonite or Crystal Shards. At a full stack of five, they can be thrown at roughly the same rate as they return, unless you are traveling quickly away from where you are aiming.

While they can technically have Modifiers, they will not gain them by being made or by being Reforged, due to their stackable nature. In order to get light discs with modifiers one must use an inventory editor such as terrariform.

Tips

 * A full stack of five Light Discs is very useful for cave exploration and gathering drops from underground enemies. Its continuous ricocheting fire, long range, and ability to have five projectiles in the air at once, along with the lack of any ammo consumption, mean that the fire key can be held continuously during travel to maintain a rather large spread "field" of indefinite fire with relatively little need to aim.

Trivia

 * This weapon is a reference to the Identity Discs in the movies Tron (1982) and Tron: Legacy (2010).
