Piglin-Bait Wither Skeleton Farm in Minecraft

Mark a real Java fortress piece volume that contains the entire x=1..9, z=1..7 pad at y=25 and its spawning clearance. Build the lower slab gallery and hopper storage.

💡 Coordinates are local and zero-based; translate the model so its upper pad lies inside a verified individual fortress piece, preferably a bridge intersection. A matching-looking platform outside that volume will not work. Confirm boundaries with a structure bounding-box tool or a disposable copy of the world before digging. Leave the chest at (10, 3, 8) clear above. The nine hoppers at y=3 all face east into it.

Enclose the nine columns at x=1..9, z=8 from above the hopper line to y=24. Build the gallery roof and the nine bottom-slab landing blocks above the hoppers at y=4.

💡 The north wall is z=7 and the south wall is z=9. On the south side, y=3 and y=4 stay open: the player can attack legs through this two-block-high slit, but 2.4-block-tall skeletons cannot exit. Place bottom slabs directly above all nine hoppers; hoppers collect drops resting on these half slabs. The bottom slabs at y=1 give the player feet height 1.5 and eye height about 3.12. Leave (10, 4, 8) empty so the chest opens; the side wall resumes above it. No fluids, ladders or ledges may enter the fall.

Place the 63 soul-soil blocks at x=1..9, z=1..7, y=25. Keep z=8 open for the drop.

💡 Soul soil has a full-height top, making the intended fall height consistent; do not replace it with lower soul sand. Every spawn-floor block and the volume above it must be in the verified individual fortress piece. Clear existing fortress floors from the future chute and remove every temporary bridge.

Build the 3x3 island at x=4..6, z=9..11, y=25 and the upper wall ring. Slab the exposed chute-wall tops on either side.

💡 The island is separated from the pad by the z=8 trench. The six bottom slabs at x=1..3 and x=7..9, z=9, y=25 stop unwanted spawns on the lower wall tops. No walking bridge may connect pad and island. The solid perimeter prevents outside ranged mobs from seeing the bait.

Place nine open top-half trapdoors at x=1..9, z=8, y=25, hinged against the north spawning pad.

💡 The trapdoors stand vertically against the pad edge, making the apparent route toward the piglin end in the drop. Keep three clear blocks above the pad surface; wither skeletons are 2.4 blocks tall. Test actual movement in a disposable world before committing to the full site preparation.

Plant one wither rose on every soul-soil block at y=26: x=1..9, z=1..7.

💡 All 63 pad positions must contain roses; uncovered positions allow other fortress mobs that can threaten the piglin or jam the system. Acquire the roses from a separate Wither encounter or wither-rose farm first. Keep temporary lighting while finishing construction and remove it only after the bait is protected.

Name an adult piglin carrying a golden sword and enclose it at (5, 26, 10) with the eight nether-brick fences shown.

💡 Use a naturally sword-equipped adult, never a baby or crossbow piglin. Rename the name tag at an anvil first, and apply it before leaving capture range. Lure the piglin over a temporary route, close the fence ring and remove the route. Fence tops are below the piglin's eye line, preserving sight toward pad mobs while stopping escape. Do not add glass, solid blocks or a low roof across that eye line. The wither skeleton shown on the pad is a natural-spawn example and must not be captured.

Place the full roof at y=29 and its bottom-slab cap at y=30. Remove temporary lights and external scaffolding.

💡 The pad surface is y=26 and the roof underside is y=29, leaving three clear blocks. The piglin has the same clearance. Verify zero block light on the rose pad and enable mob spawning on Easy, Normal or Hard. Spawn-proof all other terrain, fortress floors and caves within 128 blocks of the lower gallery; the local model cannot describe this site-dependent work. Recheck that no unfiltered spawnable ledge remains inside the chamber.
