The Light Disc is a thrown melee weapon that stacks up to five, meaning up to five can be thrown at once (although this requires the crafting of five separate light discs). Its range is the longest of all thrown weapons. When thrown, it emits a miniscule amount of blue light. The Light Disc will bounce when it hits a wall. If used in an enclosed area, it can bounce rapidly, making it extremely hard to dodge, this makes it quite an effective weapon. File:Terraria 1.1 Featured Item Light Disks
