If the information of a listed item changes, it will not be automatically updated in the Trade Market unless the seller re-registers the item.
Therefore, buyers must check the option details of the item link in the in-game chat before purchasing.
(e.g., when an item is rerolled after being listed for sale, or when a Descendant’s synchronization stats are adjusted after listing)

The first value shown for each option in the item info is the base value, which determines the grade.
The last value shown for each option in the item info is the final value, which is applied when equipped.
