You can check what specific items will bring you in the game by accessing the Item Wiki, which can be opened with CTRL + Z. There, by reading the item descriptions and checking the box content with CTRL + right-click, you can verify if a dungeon rewards you with items in a box/treasure.

Additionally, it's possible to check the rewards in the Dungeon Ranking window by opening it via Start -> Features -> Dungeon Ranking, selecting the dungeon, and paying attention to the top 3 rankings. Here, you will see the items along with their information when you hover your mouse over the item.
