Mana Flask

Mana Flask is described as a glass vial humming with arcane residue that deepens the soul's capacity to wield power, and using one grants a flat 2,000 EXP to a Unit. Like the rest of the food line, it has no combat effect beyond the EXP boost.

At 2,000 EXP, Mana Flask matches Bunny Candy for the highest flat EXP value of any food item currently in the game.

Mana Flask is the Food drop from the King's Tomb Story stage. Outside of farming that stage, it's also available through the Wandering Trader and can be purchased directly from the Gold Shop.

King's Tomb is a later Story stage, so Mana Flask typically becomes accessible once a player has progressed well past the early game.

Because Mana Flask delivers the highest flat EXP available among food items, it's best reserved for Units that need a serious level push rather than everyday top-ups. Stacking it with Bunny Candy is an efficient way to clear a large chunk of a Unit's leveling curve at once.

There's no benefit to hoarding it beyond that, since its value never scales past the fixed 2,000 EXP, so use it whenever a priority Unit needs a big leveling boost.
