-In game description

A Hi-Potion is a brew of Potion made from a finer ingredients and mixtures. It is introduced by Larsa in a short Tutorial at Giza Plains and will be available at any shop after that. Unusually, when Larsa uses the Hi-Potion, the effect seems to be at his Potion Lore augment highest upgrade, regardless the fact he has only upgrade the augment once only.

Hi-Potions easily replaces Potions mostly after the availability.

The default restoration of HP is 400, but the potency can be increase if a character activates their Potion Lore augments.
