Light Disc

Light Discs are Hardmode boomerang-type weapons that deal melee damage. Light Discs have the rare ability (along with the Bananarang) to be stacked, up to 5 in a single slot, which allows them to be rapid-fired by holding the attack button, with multiple discs in the air at once. Light Discs are quicker than other Boomerangs, and can ricochet any number of times. After approximately two seconds, the disc will return to the thrower.

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.

Light Discs cannot have Modifiers through any usual in-game means, due to their stackable nature. They can only be assigned Modifiers through use of an inventory editor. The best modifier that will stick is Godly, like other boomerangs.

Tips

 * A full stack of five Light Discs is very useful for cave exploration, gathering drops from underground enemies, and generally surviving underground in Hardmode. 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 usage key can be held continuously during travel to maintain a rather large spread "field" of indefinite protective fire with relatively little need to aim.
 * A full stack of Light Discs can be very effective when fighting monsters in small areas or rooms.
 * Crafting and selling Light Discs can be a good source of coins. Two of the three materials needed for crafting drop from The Destroyer, with said materials worth  if sold separately ( for 5 Souls of Might +   for 4 Bars). Three (3) Souls of Light add  to the total crafting cost . This in contrast to the  sell price of the Light Discs (~75% increased value).

Trivia

 * Bears a resemblance to the Identity Discs in the Tron franchise.
 * Upon entering the map function of the console/mobile versions of Terraria, a small Light Disc will briefly appear as the loading icon.
 * Because Light Discs cannot have Modifiers, a Godly Flamarang is capable of higher per-hit damage, though it lacks the Light Discs' other advantages.
