In fact, if you have the luck, you could have three in one box. The value of items in this table ranges between 10 and 100k, however, there are some other items, like the Rune the Scimitar Ornament kit (Zamorak) which could be bought for 500k gold on the Grand Exchange. Besides unique drops, there's nothing to be noted inside these caskets.
In this level players will receive 2 to four items. The unique drop table that is available in this scenario contains many more things, so the value of the loot may be different. You can find there items worth just the equivalent of a few thousand dollars, but there are also some extraordinary drops.
The first and the most expensive item is the Cape of Skulls. While it has the same base stats as Obsidian Cloak, it also features a distinct style, which is desired by a lot of players. It is why this cape cost more than 20 million dollars. There are other caps with gold prices of over 1 million, gold-trimmed monk robes , with values of several million dollars, and many other set pieces that be purchased for a few hundred thousands of gold.
Medium Clues tend to be the most popular among the RuneScape community as they have huge rewards but do not have huge of a requirement. There are a variety of items can be found inside the most well-known drop that is worthy of attention are the two Ranger Boots. The item is valued at more than 30 million dollars on Grand Exchange. Even though they don't come with that many high priced rewards in the same way as simple scrolls, they have greater chance of winning Ranger Boots than Easy Casket does in the Cape of Skulls.
Additionally there are more rewards for opening Medium Casket than you would in a straightforward one (so you could expect items like shield h3, shield H2, or helm the h3). Apart from Rangers Boots from a unique drop list, you'll find Spiked Manacles that cost over 1 million. The rest of the rewards aren't as valuable as these two items.
