Guardian farm 120k/h with crafter integration (sea lanterns/prismarine), Minecraft Java 1.21

I added a crafter design to my guardian farm to autocraft sea lanterns and all types of prismarines. This video does a quick look on the farm (about 120k drops/h), the item pickup system (minecart yeeter by Inspector Talon) and the item filters, before we go into detail how the autocrafting is set up. You can pick and choose which items you want to craft, and depending on the speed of your guardian farm you can set up a larger or smaller number of crafters. The world download has 2 crafters for sea lanterns and 1 each for prismarine, prismarine bricks and dark prismarine.

You'll need to provide black ink for dark prismarine. The world download uses a shulker box unloader for ink sacs.

Rates in the world download (may vary depending on the speed of your guardian farm):
* 4000 sea lanterns per hour
* between 1500 and 2000 of dark prismarine, prismarine and prismarine bricks each, and
* a few leftover crystals and shards (~2k/~10k) that are stored in shulker box loaders

Build time in vanilla survival was about 3 hours for the overworld side (guardian spawning) and 2-3 hours for the nether side including the crafter.

This setup will not work in Minecraft Bedrock or XBox. It works in singpleplayer Java from 1.20 (if you use the datapack providing the crafter) or from 1.21. On a Java server, as with all portal based farms, the farm works if no player is in the nether, or a second player is in the nether within 128 blocks of the kill chamber to avoid the guardians despawning immediately once they come out of the portal.
