Big damage on all opponents, ignores defenseDescription
Pandora's Box is an enemy ability and an Enemy Skill for the Enemy Skill Materia that deals heavy magical damage to all enemies and ignores Magic Defense. At 110 MP is the most expensive Enemy Skill. Pandora's Box's spell power is equal to 3.75x the base magic damage, and ignores the enemies' defenses.
The spell can only be learned from Dragon Zombie at the Northern Cave, and it is only cast as a final attack by the first Dragon Zombie the player defeats without using petrification. If the player does not learn it upon the first casting, Pandora's Box is usually impossible to obtain. It is thus advised to have all Enemy Skill Materia equipped in the battle against the first Dragon Zombie the player encounters, and not use Magic Hammer to deplete its MP. The player can set up Reflect to bounce the spell and learn it without taking damage.
Pandora's Box is an ability used by Elgo after acquiring the power of Nil. It allows him to randomly use a powerful elemental attack that hits the entire party for several damage. The spells can that appear are Neutralino a Lightning-Spell, Neutrino a Fire-Spell and Axino an Ice-Spell, named after physical particles that are related to Dark Matter. Dark Matter is an important plot-based item related to Nil, Elgo's power source.
The final boss Chaos Elgo can also use Pandora's Box, albeit it is discarded after the second phase, after Chaos Elgo uses Dark Flow on the party.
Pandora's box is an artifact in Greek mythology, taken from the myth of Pandora's creation in Hesiod's Works and Days. The "box" was actually a large jar (πίθος pithos) given to Pandora (Πανδώρα, "all-gifted", "all-giving"), which contained all the evils of the world. Pandora opened the jar and all the evils flew out, leaving only Hope inside once she had closed it again. Today the phrase "to open Pandora's box" means to perform an action that may seem small or innocent, but that turns out to have severely detrimental and far-reaching consequences.
