Therefore, if you are lucky enough to get three drops, it leaves you with 1/8 of a chance of receiving a unique.
If you are fortunate, you could find three inside one casket. The value of items on this table yields mostly from 10k to 100k, however, there are exceptions like Rune Skeletar Ornament Kit (Zamorak) that can be sold for as high as 500k gold at the Grand Exchange. In addition to unique drops, there is nothing worth mentioning within these caskets.
At this tier, players can expect to get anywhere between 2 and 4 items. The drop table unique to the game includes a wide range of buy OSRS gold items, meaning that the amount of loot available can vary. There are many items that are worth only the equivalent of a few thousand dollars, but there are also extraordinary drops.
