The Red Sun is a craftable post-Moon Lord developer broadsword. When it is swung, a large number of solar flares fall from the sky at varying speeds and angles. The flares explode after some time or upon hitting an enemy, releasing multiple homing fragments when they do. Both the flares and the fragments ignore tiles. The blade, the flares, and the fragments all inflict Holy Flames. This can be considered the upgrade of the Celestial Claymore.

Its best modifier is Legendary.
