Exclusive

Exclusive items
Players cannot have multiple of those in their inventory, although they can have as many as they want in their bank. Tip: When you carry an exclusive item, and you open a chest containing the same item, you cannot loot it. As a workaround, destroy the item in your inventory and loot the chest. Then put the new item into your bank; you can find the destroyed item in the buyback tab of any vendor.

 * Certain named items like Ring of Spell Storing and such, as carrying extensive amount of these items is considered game-breaking.
