Doryani's Machinarium is a boss-drop from the first (shallowest) Delve boss. The one that appears in Vaal City areas.

It's not guaranteed, either, so you may have to do several to get it.

I have gotten several from Zara missions in 3.13. It was one of my missing maps on the atlas until this league and was pleasantly surprised when I finally got it to comple my atlas.

Lucky you I hade to buy it :(
