Pocket

Pockets are devices that provide a variety of functions that aid the competitors in the Tower.

They are made from high purity Suspendium so they are capable of floating in areas of high Shinsoo density/viscosity.

They are classified by their ranks from A-Grade to E-Grade. An A-Grade pocket is extremely expensive. Every Regular receives an E-Grade pocket when entering the tower. This E-Grade pocket can be used to make the Shinsoo Contract with the Floor Guardians till the 40th floor, when they start climbing the Tower.

It seem that a B-Rank Pocket is enough to make a contract with every Floor-Guardian up until the 134th Floor.



Abilities
A Pocket enables the wearer to understand the different languages spoken in the Tower into Mecsethian. It appears the Pocket possesses a number of other abilities such as a timer function.

When told "Invisible Mode", the Pocket can be concealed from view. And with the command "Visible mode" it will once again become visible(Ch 2). It seems that the pocket must be in visible mode to form a contract with a guardian, which is initiated with "Contract with the Guardian"(Ch 29). When the Contract is completed, the Pocket will then display "_F contract complete"(Ch 29).

For all Regulars, pockets are really important as they allow contracts to be formed with the guardian on each floor. This is because every Position has to learn how to use Shinsoo for purposes like Shinsoo strengthening as evidenced by the World's Strongest Regular test. And usage of Shinsoo without an item requires a contract with the Guardian. (Source: | About The Tower)
