Piglin Brute

A piglin brute is a hostile mob which guards the bastion remnants. They exhibit different features from a piglin: they are much tougher, spawn with a golden axe and attack even if the player is wearing golden armor. Piglin brutes are not found with armor nor do they equip any type.

Spawning
Piglin brutes are found in bastions only upon generation.

Drops
Piglin brutes have an 8.5% chance of dropping their held item (a with random durability).

Experience
experience points are dropped upon death if killed by a player or tamed wolf.

Behavior
Piglin brutes harm players, wither skeletons, withers and are not distracted by gold related items or blocks. The Peaceful difficulty causes them to not attack. Piglin brutes do not retreat from soul fire related items, zoglins or zombified piglins. Unlike normal piglins, they don't attack adult hoglins but they can join in if other piglins are hunting a hoglin. They also don't do a "victory dance."

They are not naturally immune to fire or lava.

Like villagers and piglins, piglin brutes can open wooden doors.

Zombification
When in the Overworld or the End, piglin brutes transform into zombified piglins after 15 seconds. Upon transformation, the spawned zombified piglin has the Nausea effect for 10 seconds. This Nausea effect is purely cosmetic and has no impact on the behavior.

Trivia

 * Piglin brutes were created late in 1.16 so they were pushed to a minor release as the developers did not want to add a new feature so close to release.
 * The golden arm guard is meant to work as a "protection" and is the reason behind their high health.
 * A piglin brute is able to track the player even through a wall if they open a chest or break any gold-related block.
