To top it off the fact that you'll get more rewards
The first and most expensive one is the Cape of Skulls. Though it's got the same stats at the base of the Obsidian Cloak, it also has a very distinct look which is sought-after by a lot of OSRS GP players. This is the reason this cape can cost more than $20 million in gold. There are many other capes with gold value of over 1 million, gold trimmed monk robes worth a price of a few million, and many other set pieces that cost a few hundreds of 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. Among many items that are available inside the most well-known drop that merits attention comes from the set of Ranger Boots. This item is valued at over 30 million gold in the Grand Exchange. While medium clues may not offer as many rewards that are priced high in the same way as simple scrolls but they offer an increased chance of Ranger Boots than Easy Casket has for The Cape of Skulls.
To top it off the fact that you'll get more rewards when you open a Medium Casket than you would in a straightforward one (so you can expect things similar to shield H3, h2 or helm H3). Apart from ranger Boots from a separate drop list, you'll also get Spiked Manacles that cost over 1 million. Other benefits aren't nearly as valuable as these two items.
However, it's quite a similar unique drop table with regard to value Medium Casket which ranges from difficult difficulty, it also gives you the possibility of rolling from the hugely rare table. There are a range of extremely expensive items such as 3rd Age Equipment and Gilded Parts valued at hundreds, or even thousands of million (like 3rd Age Platebody). Additionally, items from a unique drop table are valuable as there are four items that cost more than a million gold. On top of that there are more rolls for rewards with a hard Clue than you do with a Medium One which means that in general the scrolls will give higher drops.
Similar to the previous box, you'll have a chance to roll for exclusive and rare items that carry an estimated value of tens or even hundreds of millions. The main difference between this box and the previous one is that you have better chances of receiving Gilded drops, and a lesser chance of Third Age items.
There are also less regular drops that cheap RS gold have a low value overall and more of them having 1-10 million values like Fury Ornament Kit, Saradomin Ornament Kit, Ranger Chaps, Ranger Gloves, Sagacious Spectacles Fremennik Kilt Black Tuxedo Jacket, White Tuxedo Jacket or Dark Trousers.
