Q. What is the use of iron chains?

Answer

A punishment consisting of being chained to a large iron ball is common. A free-standing chain may materialize, depending on the strategy for undoing own punishment. When an iron golem is slain or a drawbridge is demolished, iron chains are often left behind as evidence. Inventories of iron chains are organized under the "Chains" heading. To hold, pull, hoist, haul, convey, and transmit power, among other things, a chain is a series of links, typically made of metal, connected together to form a flexible connector. The first three types of chains are experiencing a decline in popularity and are now mostly reserved for exceptional circumstances.
