I think you have posted on the wrong forum section...
You get it from dungeons, you can't craft it. It's a dungeon-only reward.
Try looking at the topics below, if it's a talk page for a article it will automatically be noted down there what article he is talking about.
I see, sorry then. But the currently only way to acquire this item is via dungeons (Slider's Labyrinth) or Continuum Orbs (Random drops or by acquiring Keys + Dungeon Chests)
