Cube Recipe: Elemental Rings

I have seen those recipes which are for rolling Elemental Rings. My Idea is why do they exist? Makes no sense to me. Later I heard of a unique Ring giving Elemental Resistances Like 100 all Res, +15Max Res etc.
Maybe there is something hidden. Like a cube recipe adding a

The Stone of Jordan and all of these other crafted rings?

"** The Contricting Ring is not and never has been droppable. We have it listed on our Unique Rings page, and the ring's full stats are listed in the game files, but it has a 0, instead of a 1, in the "completed" column in uniqueitems.txt, the actual game file that sets the properties on Unique items, which makes it undroppable. "

You can change the value in the txt file though to make it dropable in SP. I have not checked the other stats so I don't know which, if any, monsters would be able to drop it, and at what odds.

The reason why this item has never been enabled is that it would break the whole game.

The ring recipes are also not the worst cube recipes.
Those can spawn with a suffix. Imagine you are low on light res and you cube one and it gives you a ring with 30 light res and a nice suffix. Pretty neat, especially if you are playing SSF HC.

The cubed resistance rings are still useful for leveling characters, because it's hard to optimize your build at that stage. Fire & lightning are especially helpful, because both of those elements can have high burst damage.

If you have Hero Editor, it is possible to give yourself the Constricting Ring in SP, but it is absolutely broken.
