Wand

A Wand (완드, wandeu; "Wand) is an item with the ability to create/collect an amount of Shinsoo.

The ability to control Shinsoo is very rare, and most Regular and Ranker use special items when they wish to manipulate larger amounts of shinsoo. These items are called Wands.

A Wand and its Contract
When a Wand is made by its craftmaster, a part of the crafting is for it to come under Contract with one or more guardians. So, the wand can only be used on Floors where it has a Contract with a Guardian. If a Wand is under contract of the Guardians of Floors 2-31, then it will not be able to manipulate any Shinsoo on the 32rd floor and beyond.

The Contract does not only specify the Floor/s (or part of a Floor/s) which the wand can be used, but also the fixed amount of Shinsoo that can be manipulated. This limitation is likely specified using the three terms for measuring Shinsoo: Baang, Myun and Soo.

Notes and Trivia

 * Wands can be in any shape, as seen by Yeongsuk's rings.
