Chain

Chains are necessary components for various crafting recipes. It is necessary to create items such as the Grappling Hook, Sawmill, all types of Watches, and Chandeliers. Chains can be placed and used like Rope and offer the same climbing speed (1,000ft in 14 seconds), however you can place it at a slightly longer range (+3 tiles), although you cannot turn them into coils like ropes can. Chains are not considered a full block, therefore furniture cannot be placed upon it and cannot count as a wall in a Room. Making unneeded iron or lead into chains can result in a great profit of per bar, though in Hardmode using the bars farming Mechanical Bosses can be even more profitable.
