Prismarine Factory

 

The Prismarine Factory is located over a former Ocean Monument just south of West Elthon Fishing Village. It is accessible via rail or the Nether. It is the largest factory that J and I built together. We crated a perimeter around an Ocean Monument, drained the water using slime block flying machines and then sponges. It originally used a long-bay set-up to spawn the Guardians, but I later changed it to a smaller four-pod system that can be turned on and off from the control tower. The internal wall design is based on Guardfall from the Hermitcraft server.

The control tower and sorting system. Items come up through the middle of the tower and are visible in the glass.

A view of the spawn pods through the floor of the control tower. You can see the target zones below each pod.

Drops from the Guardians are collected via this hopper minecart system. The rails extend all the way under the floor of the target zones. They instantly dispense the items into a water stream and are sent up the control tower.

This helicopter is an AFK spot for a fairly inefficient Drowned farm. Under the water to the left you can see the ocean floor rail line which goes to the Omega Deep train station.
