Sculk sensor drop raid farm

A raid farm built over ocean or high in the sky, where the raid spawns in a 3x1 chamber above the farm. A sculk sensor hears the raiders spawn and opens the floor under them, so they drop onto a kill platform and die to one hit from a Looting 3 sword. Ravagers get pulled into lava on the side. When the raid is done you drink another ominous bottle and the next one starts straight away, which is what the repeating in the name means. One villager with a workstation and a bed is the whole village. Placement is strict: you stand at chunk relative 06 00 09 facing east, and the creator says that part is not optional.

Stand at chunk relative 06 00 09 facing east. The creator tested it in the sky at y288 with the platform at y287 and had no failed raids, so building it high up is fine.
Do not use Fire Aspect or Knockback on the sword. Fire burns the armor stand and knockback shoves it out of place, and without the stand you cannot hit the raiders.
If the raid bar fills and then disappears with nothing spawning, take out the glass block above the composter so the villager can reach his workstation, trade with him once to lock the profession in, then remove the bed after he has slept.
The other fix for empty raids is the glass above the spawn block. One builder got it working by removing that layer, another by not building the base out of glass at all.
The schematic has a second dispenser above the player with lava in it and a button, for clearing mobs off you safely. The creator says he forgot to show it in the video.
Use a barrel and the villager can lose his profession, a chest instead avoids that. Bottles need to be bad omen 3 or higher.
