Corrupt Vesta's plateskirt is a rare drop from killing Revenants in the Forinthry Dungeon, or as a very rare drop from the Chaos Elemental. It requires level 40 Defence but has level 65 bonuses and is classed as PvP armour. It lasts only for 15 minutes of wearing. After the time is up, the plateskirt will vanish.
If a corrupt Vesta's plateskirt is degraded and then lost in any situation, the highest amount of coins received is 494,882. As with all degraded ancient warrior items, it may be useful to do this instead of alching because players who do this will gain more coins than they would get from alching it.
Once you wear this item for longer than around 30 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 instantly, also rendering it untradeable.
