(Desktop, Console and Mobile versions) The Light Disc attacking Target Dummies and ricocheting off blocks.

The Light Disc is a Hardmode, post-The Destroyer boomerang. It does not necessarily return immediately upon contact with objects, but instead can bounce off blocks before returning. Unlike most boomerangs, it does not have to return to the player before being fired, with a maximum of six Light Discs that can be thrown out at one time.

Its best modifier is Godly or Demonic. Both modifiers increase the average damage output by the same amount. However, Ruthless might be preferred if the player already has very high critical strike chance.

Notes

  • The Light Disc can travel for 0.5 seconds before it starts decelerating, and eventually turning around to return towards the player. This results in having a maximum range of roughly 32.85 tiles.[1]
    • Melee speed bonuses increase the boomerang's velocity, which in turn increases its range.
      • Conversely, liquids will slow down the boomerang and reduce its range.
    • As soon as the boomerang begins decelerating, it gains infinite piercing and becomes capable of going through solid tiles. This allows it to hit enemies multiple times near end of its maximum range and slightly penetrate into tiles.
  • The Light Disc has a top speed of 82 mph when returning to the player, and can only exist for up to 1 minute before despawning. It will also despawn if its distance from the player is more than 187.5 tiles.

Tips

  • Light Discs can be very effective when fighting monsters in small spaces.

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 Old-gen console version and pre-1.3 Mobile version Mobile version of Terraria.
  • Mobile version 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.
