Minecraft Legends:Piglin Key

"These keys open piglin chests which have been locked to prevent their valuable contents from being stolen. Though any piglin may be found carrying them, bosses and tougher units, especially those found roaming the world, are the best place to look. Their crude craftsmanship causes them to break after use, so you'll need to find a new one for each chest you open."
