[view] • Chain armor is a normally-uncraftable form of armor. It can only be made using Fire with cheats, as that is the only way to obtain a fire block. Chain armor is stronger than Leather or Gold armor. The only way to legitimately obtain Chain Armor is via Villager trading, or a rare drop from zombies and skeletons,albeit very damaged. However, you can also use the command "/give @p fire <amount>". Chain Armor is stronger then Leather.
To craft Chain Armor you need to use fire blocks, putting them in the usual armor shape, but as of 1.3.1, Chain armor can be obtained through the use of villager trading, using commands, or it can be dropped by zombies, or skeletons (if the mob is wearing the armor).
