I'm a new player and I'm struggling to understand how the process works...

So, for example, if I wanted the new Rao Togi +1 I would have to do... what exactly?

The update notes don't make any sense to me. What do I do with the Shura Togi +1, Dryadic Abjuration: Body and Umbral Marrow? They get synergized back into a regular old Cursed Togi -1?

Sorry. Can somebody chime in here? Can a Community Rep say explain this? I'm totally lost.
