Physical abilities use up HP whilst elemental and support magic use SP. By exploiting an enemy's weakness or performing a critical attack, characters can knock the opponent down, granting that character an extra turn, though enemies can also take advantage of an ally's weakness to gain an additional turn.[4] If the player manages to knock all opponents down, they may be granted the opportunity to perform an All-Out Attack, in which all able party members assault the enemies for massive damage.[5] Allies who lose all of their HP can be revived using revival items and abilities, but if the protagonist loses all of their HP, the game will end.
