Check Jorgin.

yes, it's a random Craicic Spider Crab IF you want to choose where to craft

Jorgin gets you random rares with the craft (and random shitty rolls with it).

I also found items from the Delve with the craft, also totally shit rolls with it-->vendor

E: Craicic Spider Crab to open the portal, then you have to deal with the boss and if you fail, then its bye-bye craft :)
