User:Explorer for Treasure/Abandoned Piglin Mineshafts

Abandoned Piglin Mineshafts are large, underground generated structures found in all The Nether Biomes except Soul Sand Valley. As their name suggests, they are rare maze-like complexes of tunnels, however unlike Mineshafts in the Overworld they do not have any ores exposed on the walls and floor.

Generation
Abandoned Piglin Mineshafts generate naturally in The Nether between y coordinates 8 and 22. Unlike Mineshafts the walls and ceiling (made of Netherrack) are part of the structure so odd generation is impossible.

Structure
Abandoned Piglin Mineshafts consist of the following features:


 * Lava Tube A Small Room on the surface made of Polished Blackstone Bricks with a hole in the floor filled with lava going down to the actual mineshaft.
 * Furnace Room A 5x5 Room adjacent to a Lava Tube made of Polished Blackstone Bricks containing 3 furnaces, 1 chest and a crafting table.
 * Starting point A a large room with a flat 10x10 floor and ceiling and 3 blocks high walls, made of Polished Blackstone Bricks It will have the bottom of the lava tube and up to 3 exits, usually one in each direction. Each Abandoned Piglin Mineshaft only generates one starting point. Furthermore it may have up to 6 chests.
 * Corridors 3×3 tunnels supported by wooden reinforcements constructed with planks and fences (wood type is the chosen by the closes biome with Natural Nether Wood to the middle of the lava tube - if both are equal distance one is picked random for the hole mineshaft). The passageways are connected by incomplete rail systems on the ground, on which minecarts with chests may generate.
 * Crossings - 5x5 intersections supported by wooden beams.

Furnaces
In the fuel box there is a 60% chance of there being 1-10 coal. In the item to be smelted box there is a 30% chance of there being 1-5 Ancient Debris however if coal and ancient debris are meant to appear one of them will be picked 50/50 to override the other. Furthermore there is a 10% chance of there being 1-3 Nether Scraps in the smelted box.

Trivia

 * The corridors are perfect 3x3 Netherrack tunnels with support beams but surely there would be holes where Nether Gold Ore and Netherite had been mined out by Piglins ? Why would they go to the trouble of filling them in unless they were going through lava ? Same goes for changing walls to be Netherrack that would normally be Blackstone
