Six villager raid farm

Raid farm built on six villagers in composter chambers, where a hopper clock takes their jobs away and gives them back to restart raid after raid. Ominous bottles start each one, pistons drop the raiders down a glass shaft, and you kill them at an armor stand. The composter and armor stand part of the design is Firestorm's. It is the fussiest farm here by a distance: it does not run as shown in the video, and the comment section is a repair manual that most builders had to work through before getting a single raid out of it. It is also the only farm here that consumes more of its starting item than it produces.

• Put 64 and 50 items in the hopper clock, not the 64 and 28 the video uses. This is the most repeated fix on the whole video and it is what stops the raid bar filling up and then vanishing.
• Move the composters to the side of each villager chamber that the slime blocks do not push. Otherwise the villagers lose their jobs mid raid and the raid cancels itself.
• Stop the clock and check that every villager has a job before starting it again.
• Move the lowest pistons up a few blocks. Pillagers that die from the fall instead of your sword drop no emeralds at all.
• Swap the sticky pistons at the shifting floor layer for regular pistons, and make sure that floor can actually move when the redstone blocks lift and drop.
• The video misses a log. Replace one leaf with a log so the redstone signal carries up the pole, and put your render and simulation distance above 14.
