Piglin

Piglins are neutral mobs that inhabit the Nether.

Behavior
Piglins are naturally hostile to the player, unless the player wears gold armor. They also attack wither skeletons and adult hoglins. They have an adult and baby variant, as zombie pigmen and hoglins.

Even if the player wears gold armor, piglins will become aggravated towards the player if they open a chest containing any item crafted with or related to gold near the piglin. The player will be able to "barter" (similar to trading) with the player. To barter with piglins, players have to throw them a gold ingot and piglins will throw them an item in exchange.

When in the Overworld, Piglins will transform into Zombie Pigmen after about 20 seconds. When they transform, they will lose all their armor and held items and will be given a Golden Sword as with regular Zombie Pigmen. Upon transformation, the newly spawned Zombie Pigman will have the Nausea effect for about 10 seconds.

Sometimes a Piglin can spawn wearing golden armour.

Bartering
To barter with piglins, players have to throw them a gold ingot and piglins will throw them an item in exchange. Those items are Flint, Rotten Flesh, Leather, Soul Sand, Brown Mushroom, Red Mushroom, Gravel, Nether Brick, Shroomlight, Fire Charge, Raw Porkchop, Obsidian, Glowstone Dust, (Very Rare) Warped Nylium, (Very Rare) Crimson Nylium, Warped Fungi, Crimson Fungi, Magma Cream, Nether Quartz and Ender Pearl.

Drops
When killed, piglins drop: Piglins currently do not drop any items.
