Luminite

Luminite is an ore that drops from the Moon Lord Boss, usually in stacks of 70-90 (90-110 in Expert Mode). It can be used to craft Luminite Bars, which can then be used to make many end-game items, such as the Solar, Nebula, Vortex, and Stardust tools and armor.

Crafting all items requires 1088 Luminite. This means defeating the Moon Lord 16 times in normal mode, or 13 times in Expert Mode.

Trivia

 * It is the only ore that doesn't need any kind of Furnace or Forge in order to be smelted into bars.
