Astral Bar

Astral Bars are Hardmode bars made with 2 Astral Ore and 3 Stardust per bar. They are primarily used to create Astral-themed gear and are additionally used to craft upgrades to weapons, such as the Radiant Star. As well as being used to craft weapons, Astral Bars are used to craft the Ethereal Core, a consumable that can permanently raise the player's maximum mana.
