One thing you can do to find out about legendary items is go to one of the pools beyond the Ebon Labyrinth bosses and examine the options available. It won't tell you everything, but it will tell you what they are and what you need to enchant to create them.
You can also have a child with the pompous futacorn in the woods. The child apparently enchants stuff, but I've never explored this option.
