The corrupt dragon plateskirt was released on 15 October2008 along with PvP worlds. It is the strongest plateskirt available to non-members, but it crumbles to dust after 30 minutes of wearing. Because of this, the skirt (along with most other corrupt dragon armour) is often sold as soon as a player obtains it. It requires 60 Defence to wear. For free players however, this is a marginally better choice of leg armour, as it is as strong as the dragon plateskirt, corrupt dragon platelegs, and non-corrupt dragon platelegs, except slightly cheaper.
Players can obtain this item either by trading with another player, or by 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.
