Solar Fragment

The Solar Fragment is a Hardmode, post-Lunatic Cultist crafting material. It is one of the four Lunar Fragments, dropped from the Solar Pillar during the Lunar Events in stacks of 12–60 /. Solar Fragments can be used to craft Solar Flare armor, an end-game armor set that benefits all types of melee weapons, as well as Solar-themed tools, weapons, wings, etc.

Crafting all items requires 121 Solar Fragments and 68 Luminite Bars (272 Luminite), which necessitates defeating the Solar Pillar at least 3–11 / times (note that the Solar Fragment can also be crafted from the other fragments) and fighting the Moon Lord at least 4 /  times.
