PSA because I don't see these spawn enough. Each Goblin Cartel has a rare spawn connected to it.
You have to be Renown 6 and have a weekly contract for that certain cartel. After talking to an NPC, there is a small event that needs to be completed to spawn them. Here's a quick map I made.
Bilgewater: M.A.G.N.O. (40,22)
Speak to Ragzy Cashgrab on the roof to start the event. Collect scrap until the bar is filled to 100%. This rare spawn takes a little while to pop up, so just wait.
Blackwater: Voltstrike the Charged (62,26)
Speak to Boatwright Frankle on the docks to start the event. Collect Chunks of Charged Glass and deposit it into the machine until 100%. Sometimes WQ in this zone will interfere with the event.
Steamwheedle: Giovante (31,75)
Speak to the Noggenfogger Recall Technician to start the event (she's a goblin with a clipboard). Collect and use the different items in the area on the customers to help them out until progress is 100%.
Venture Co.: Scrapchewer (57,79)
Speak to Scrapminer Krazzik to start the event (he's a goblin wearing a hard hat). Collect batteries to put into the drill rig. Once 100 batteries have been collected, the rare will spawn.
