Ghast Farms that use Nether Portals
Due to the lag that is caused when Ghasts go through a Nether Portal into the overworld, we have made some modifications to Ghast Farm mechanics.
Above is the overworld part of a Ghast Farm. On V+ all you need is one small Nether Portal and hoppers on either side to pick up the Ghast drops that come through. You could easily direct the drops into a sorting system using water streams around the portal.
