Crying Obsidian

Crying obsidian is a variant of obsidian currently only obtained via bartering. It was originally going to be added in an early beta version of Minecraft as a means of setting the player's spawnpoint, but was replaced with beds.

Obtaining
Crying Obsidian can only be mined with a diamond or netherite pickaxe. Breaking this block with anything else will cause the block to drop nothing.

Bartering
Piglins may rarely barter crying obsidian.

Usage
Crying Obsidian is currently used only for decoration. It will get a use in the future.
