Llama aggro gold farm

Zombified piglin gold farm for 1.21, Java only. A magma tower in the nether does the spawning, a llama at the top spits at two piglins locked in boats, and the anger passes down the whole stack so they path into the portals. They come out in the overworld, ride an elevator back up and go through a second portal into a boat looting chamber, where you swing a looting sword at an armor stand. Crafters turn the nuggets and ingots into blocks and a shulker loader packs them away. In multiplayer nobody else can be in the overworld, or you need a second player or a carpet bot standing at the elevator. A chunk loader will not do it, the piglins already load those chunks themselves.

At 28:22 the section is 26 blocks, not 24, and at 47:33 the nether coordinates are multiplied by 8, not divided. Both are in the creator's pinned comment along with the rest of the corrections.
Build from the litematica schematic and use the video only as reference. The thread is close to unanimous that the tutorial itself is very hard to see.
Do not use bamboo rafts. Items do not pass through them, so most of the drops never reach the sorters.
From 1.21.11 use the new overworld elevator from the description. The old ladder version broke when hostile mob pathfinding changed, and the piglins pile up until the server crashes.
Use the carpet mod autoclicker, not a client side one, or the armor stand breaks. About twenty builders hit this.
Do not use a wandering trader's llama, it despawns. Tame one or breed from it first.
