Celestial Merchant

After you beat the Moon Lord for the first time, you can choose which Merchant you want: Solar Merchant, Vortex Merchant, Nebula Merchant or Stardust Merchant. You can buy everything made out of the fragments, including the unobtainable ones. They look like The Drakanian, Vortexian, Stargazer or Predictor. They defend themselves with weaker versions of the Celestial Weapons. They Also sell Luminite Ore.
