Potential is one of the five main stats of a character. How well a character can use/sync with their Mage Item is determined by this stat. It is crucial to one's ability to transform and retain it.
A unique stat that doesn't follow the same principles as the other four stats.
It determines the time of a transformation. Having lower than 20 potential will also grant an hour of transformation time. Potential is equivalent or used to determine "hit points" in certain systems such as Disphere's or the Academy's Duel system. It is important to those with Familiars. For battles this determines stamina/energy (Low = tire easily, high = maintains mage form longer without strain).
