The Light Disc attacking Target Dummies.
The Light Disc is a Hardmode boomerang-type weapon that deals melee damage. It returns to the owner once it hits an enemy or reaches its maximum range. Light Disc physics are similar to those of the Thorn Chakram, being able to bounce off solid blocks, though Light Discs have nearly twice the range. It also has a glowing texture, allowing it to be seen in complete darkness.
On the 
Desktop version, 
Console version, and 
Mobile version, the Light Disc cannot be stacked, and can be rapidly fired, with a maximum of 6 Light Discs being thrown out at the same time. It also has a blue trail effect when thrown. Its best modifier is Godly or Demonic. Both modifiers increase the average damage output by the same amount.
On the 
Old-gen console version and Nintendo 3DS
version, the Light Disc can be stacked up to 5 in one slot. The bigger the stack is, the more can be thrown out at the same time. The Light Disc cannot be reforged, and therefore cannot have modifiers.

Notes
Two examples of ricocheting with the Light Disc.
- Like most other projectiles, liquids slow their travel speed.
- Due to their infinite ricochet ability, Light Discs ricocheting at acute angles in small enclosure can cause excessive ricochets and particles, which might cause lag.
- Firing a Light Disc directly against a wall grants it the ability to penetrate a 1-block wide wall directly behind the player.
Tips
- 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 560 if sold separately (4 for 5 Souls of Might + 160 for 4 Hallowed Bars). Three Souls of Light add 6 to the total sell price (566). The 10 sell price of the Light Discs nets about 77% more profit.
- The Light Discs are quite effective against the Twins since they usually mirror the player's movement or chase them directly, setting up for easy hits.
Trivia
- Light Discs resemble identity discs from the 1982 American science fiction action-adventure movie Tron. Their tooltip, 'Greetings, programs!', is a quote from the movie.
- The Light Disc's sprite is used as a loading icon of the map on the Old-gen console version and pre-1.3 Mobile version of Terraria.
- Light Discs can be assigned modifiers through use of an inventory editor. The best modifier that will stick is Godly, like other boomerangs.
- Prior to Mobile 1.2.6508 (the 1.2 equivalent), one could throw an infinite amount (though they will return to the player) of Light Discs regardless of the stack amount.
History
- Desktop 1.4.4:
- Is now a single item, not 5 stacked items. As a result, it can now have modifiers.
- Recipe cost has been multiplied by 5 (since the player now only needs to craft 1): Now requires 20 Hallowed Bars instead of 4, 15 Souls of Light instead of 3, and 25 Souls of Might instead of 5. Similarly, it now sells for 5× as much (30 instead of 6).
- Damage increased from 57 to 60.
- Use time reduced from 15 to 14.
- Can now shoot up to 6 discs at once instead of 5.
- Projectile speed/distance increased from 13 to 16.
- Console 1.01: Can no longer throw an unlimited number of Light Discs (even when only 1 was in inventory).
- Mobile 1.2.12773: Removed as the loading icon upon entering the map function, a small Light Disc used to briefly appear (version?).
- Mobile-Release: Introduced (? first mention in the page history was after the 1.1.5536 update).
