This Magic allows the users to store items in a pocket dimension so they can easily summon it at any time, even during battle, which gives them a high level of flexibility in combat. However, there is a limit to how much the pocket dimension can store. Requip can be used for simple or combat-related purposes. Some users may just choose to use it to change their clothing. More skilled users are able to Requip different weapons in battle, and it is even possible to Requip armors in the midst of battle, although the only Mage to ever do this is Erza Scarlet.
The Knight: A type of Requip that allows the user to store weapons and armors in pocket dimensions and summon them during battle, giving them greater diversity and creativity to adapt to any environment possible.
