W - Item duplication bug The W - Item duplication bug is a useful glitch in " Final Fantasy VII " . The W - Item Materia is a Command Materia that allows a character to use two items in one turn . To make the glitch work , the player must enter a battle and select any item they wish to duplicate , confirm it , and then select another item ( it does not matter which one ) . When the arrow is over a character ' s head , the player must cancel the item with or , depending on controller configuration ( it does not work with ) . Every time one does this , the amount of the first item will go up by one . The glitch cannot exceed the 99 item cap . Because one can make 99 of any battle item , the glitch is obviously extremely useful . A player can boost their inventory to have 99 Elixirs and Megalixirs in a matter of minutes . It is also the only way to get 99 Dragon Fangs . The player can also duplicate the rather expensive Sylkis Green | Sylkis Greens rather than having to buy the entire load from Chocobo Sage . This way the player can also easily earn money by duplicating items and then selling them . The glitch has a potential drawback ; if the first item is selected , it is removed from the inventory even if the item command is canceled and the item is not used . Some ports of the game may have the bug fixed . Variations . Morph glitch . The W - Item glitch can be modified to duplicate other items that do not normally allow selection in the battle screen window . For the morph glitch , any item an enemy can be morphed into can be duplicated , provided there are additional enemies so that the battle does not end upon morphing . To accomplish this , the player must have a single use item of no importance at the top of the inventory ( e . g . a Potion ) . The player must enter the appropriate fight and order a character to kill the enemy they want the item from via the Morph command . Before the morph action is executed , they must use W - Item with another character , selecting the Potion and who to use it on , and then waiting before selecting a second item . Once the morph has been accomplished , the morphed item ( e . g . a Power Source ) will go to the top of the inventory . Now the player can select another item ( e . g . an X - Potion ) , deselect , select , deselect , etc . The Power Source , normally not possible to be duplicated , will now increase in value . The glitch ' s primary use is to easily obtain 99 sources in a single fight . This works for Speed , Luck , Power and Guard Sources , which can be obtained from enemies that appear in groups . Magic Sources can be obtained through a variation of the trick — 8 eye enemies at Gold Saucer Battle Square carry them , and appear in pairs . The player should use Stop or Sleepel on one enemy , then utilize the Morph - Command Counter technique while having character command selection over W - Item . When the morph attack takes place automatically as a counterattack , even a single party member can use the W - Item trick provided the second enemy does not awaken and attack too quickly ( causing the character to auto - counter and end the fight too early ) . Lastly , Mind Sources are the most difficult to obtain , as they can only be morphed from Serpents in Gelnika or Battle Square , or Dragon Riders in the Whirlwind Maze , which can only be fought before the W - Item Materia is found . However , duplicating Mind Sources is still not impossible . If playing on the PlayStation , opening the lid just as the morph occurs can allow time to duplicate the item . In addition , there is a method for PlayStation Network players too : Player must enter a fight with a Serpent where one character has a Morph - Final Attack combination , and a second character has a combination of Full Cure - Final Attack along with a Master Magic - Quadra Magic combination ( this means a Final Attack Full Cure will occur four times ) . The party must whittle the Serpent down to low HP , and also whittle the two party members with Final Attack down to HP Critical ( the third party member should have the W - Item ) . The player should allow the Serpent to kill off the two low - HP party members in one attack ( Serpent is likely to use the Aqualung attack on low health ) . As the two characters die , the first will Morph the enemy first ( providing they have their Final Attack Materia combo higher in the slot inventory than the other party member ) . The next character can then perform their final attack , but the game will only process the command if it is directed at a party member ( i . e . the enemy is long gone after one final attack already , so a lengthy summon like Phoenix cannot be executed ) . To keep this command running for as long as possible , a magic such as Full Cure four times will give the W - Item player an opportunity to quickly duplicate the Mind Sources after the enemy has been morphed . With luck , one can still get around 80 Mind Sources by the time the four Full Cures have been executed and the battle ends . Naturally , additional Final Attack Materia linked to other curative magic spells will prolong the process even further ( see video ) . Steal glitch . The steal glitch works in a similar fashion , but can work on virtually any item in the game . However , the glitch is difficult to control . One enters a fight against an enemy who can steal from the party ( e . g . a Magic Pot , or Bandit ) . The enemy steals the item the player wishes to duplicate ( it is impossible to control which item is stolen ) . The enemy is then killed , and during the killing another character begins the W - Item command . After the enemy dies , the item will be returned to the top of the inventory , and from there can be duplicated in the normal fashion . This method will work for any item in the game except for the following which are limited to one : To perform the W - Item duplication bug with the steal glitch a certain number of conditions must be met . A hypothetical scenario would play out like this : The player faces two Magic Pots and wants them to steal a Mystile from the party . The player equips the other Mystiles so only one remains in the item menu . The player arranges the items to put a Maiden ' s Kiss in the first position of the list , and the player has only one Maiden ' s Kiss . The player attacks the pots until one steals the Mystile , making sure the other pot doesn ' t run away . After feeding them two Elixirs , the player kills the Magic Pot that stole the Mystile , and has the character with W - Item start the duplication trick by using Maiden ' s Kiss , then using the second item in the list after Mystile has been returned to the top . The Mystile is duplicated because the game believes it is the Maiden ' s Kiss . Throw glitch . It is also possible to duplicate weapons . The player must enter a fight and order one character to KO another . Before the party member initiates their attack , the player must have the victim party member prepare to throw a weapon ( e . g . Ultima Weapon ) to remove the item from the inventory . As the party member is KO ' ed before the actual throw is executed , the item will return to the top of the inventory . From there , normal W - item duplication can be executed . 198 variation . It is also possible to get 198 units of a single item by acquiring a second stock of the same item . The player must equip one character with Steal and another one with W - Item . The player must also have one copy of the battle item they wish to duplicate ( the same that needs to be stolen ) , and there must be at least one empty slot in the inventory above the selected item . The trick is to have a character initiate the steal , but not wait for the steal action to finish . After the Steal command has been initiated , but before the item is stolen , the character with the W - Item Materia has to select and use the single item in the inventory ( the same item the other character is going to steal ) , then wait for the steal action to finish . After a successful steal the item will appear in the inventory , and since the player no longer had any left , the game will place it in the first empty slot . The player can then continue with the W - Item trick and the item will reappear where it was before it was used , ending up with two different stocks of the same item .
