Greater Mana Potion

The Greater Mana Potion is a potion that restores 200 mana upon use and is the most potent of all mana restoration items. Unlike most potions, Greater Mana Potions cannot be crafted. They can only be purchased from the Wizard, who only moves in after being rescued in a Hardmode world.

As of 1.2.1.2, consuming any Mana Potion (Greater, Regular, or Lesser) will not trigger the Potion Sickness debuff, allowing magic-oriented players greater longevity in long battles and boss fights. Equipping a Mana Flower lets a player consume mana potions automatically.
