Whats the recipe?
 

I need to know the recipe to upgrade items i know it has to do with a Lem / Ko rune but when i put them into the cube to combine them nothing happens...amn i missing something

That and here is the original site for most of the Cube Recipes, Arreat Summit Cube Recipes

And you wonder why the makers, Blizzard, would ever putt that on their site.
