In Rohan, a cursed piece is a crafted item that can not be worn or utilized by it. All cursed items require very high level crafting skills to create. For example, skill above 90 is needed in the primary crafting guild, and some pieces also require a secondary crafting skill of 50-60. These cursed items are not rare or Exclusive, and can be sold in the Auction House under the others or cursed Items category.
The ingredients required to create a cursed item(rohan gold) are often expensive on their own, causing many of the cursed items to cost hundreds of thousands. If purchased at the Auction House, all of the cursed items that can be turned into armor also have a high quality version. These high quality cursed items are notated with a -1 after the name, which is then turned into the high quality +1 armor. For example, the standard item to use with the Aquarian Abjuration: Head is the Cursed Crown, which creates a Zenith Crown.
If the abjuration item is instead used with the high quality Cursed Crown -1, it becomes the more powerful Zenith Crown +1 when it is uncured. There is no restriction on how many items a character(Rohan powerleveling) can have from the abjuration sets, although since the armor is all rare, only one copy of each piece of armor can be obtained.
