Luminite Bar

Luminite Bars are a type of bar used to craft all four sets of end-game armor and tools, as well as other end-game items. To craft one of everything (excluding the ammo) you will need 317 Luminite Bars, or 1,268 Luminite. To get that, you will need to kill the Moon Lord 15-19 times in normal mode, or 12-15 times in Expert Mode.
