Datalog . " Antimatter Manipulation Principle ( AMP ) forms the foundation for variety of technological wonders , enabling phenomena ranging from phase - space interference to the manipulation of gravitational force . " " Humans ordinarily lack the means to wield magic , but through the use of manadrives — another product of the principle — it is possible to synthesize its effects . " Appearances . The Grav - Con Unit is a military - issue manadrive device , which generates a modified gravity field that allows whoever the field surrounds to perform feats of near - superhuman agility and survive jumps from immense heights . Lightning uses it in the Purge train to break free of her captors , and in Hanging Edge to jump and land safely from a skybridge . Sazh follows her and survives due to the residual landing circle . Later in Eden the party uses it to descend into the streets from the skyway . The technology allows the user to use powers similar to magic that is otherwise only usable by l ' Cie and fal ' Cie . Manadrives can also be charged and then used to unleash a powerful magical attack , though this technique is only used by some high - ranking Sanctum forces . A variant of this is the Gravity Bomb , which works in a similar way , but is used as a replacement for rappel cables that are typically used by real life military units for raids . In Lake Bresha , while Snow is trying to get Serah out of her crystal prison , PSICOM airships fly in . PSICOM units jump off and land safely using these devices . Cocoon ' s airships and gunships use manadrives as a propulsion system . The PSICOM summon portals are generally used for transporting genetically - modified monsters from the Cocoon labs to the battlefield . The gates are used by Barthandelus to transport monsters from the Fifth Ark to Eden . The strength boosting emblems on Snow ' s coat are AMP technology , and Hope ' s boomerangs use civilian AMP technology , allowing him to manipulate their direction once they have been thrown . In " " , it is revealed the matter transportation system laid throughout Cocoon used AMP technology , and densely populated areas were equipped with large gravitational control devices in case any airships crashed . In " " , it is revealed that AMP technology can control Chaos , but the research into this use was never completed as the researchers disappeared . Though not directly stated , it may be that the Ark of the manmade Cocoon was where the research took place , and utilizes AMP technology to halt the flow of time . Other appearances .
