Most free players choose not to use this due to the high cost of the item. However, in a player vs. player situation, it is the only armour known to be able to adequately defend on its own against the Gravite 2h sword.
Players can obtain this item either by trading with another player, or receiving it as a very rare drop from killing Revenants or the Chaos Elemental.
Warning: Once you wear this item for longer than a few seconds, it will have the word (deg) added to its name and it becomes untradeable. Using this item in combat adds the (deg) to its name almost instantly, also rendering it untradeable.
Interestingly, despite its name and stats, Corrupt dragon chainbody looks much more similar to a rusted Dragon platebody missing one of the shoulder-pads than the Dragon chainbody. This can be seen in the overall shape of the chainbody.
