Purpur Block

"Purpur is one of the strangest and most otherworldly materials in Minecraft, found in a fittingly strange and otherworldy dimension: the End. The blocks themselves can be crafted from popped chorus fruits, which have been harvested from the angular cacti-like chorus trees, and then gently smelted. But these are no ordinary fruits - when eaten they can teleport the player a short distance. Even weirder, purpur blocks make the perfect camouflage for the mollusc-like shulkers, emerging from their purpurish shells to launch homing missiles at the player."

Purpur blocks and purpur pillars are decorative blocks that are naturally generated in end city dungeons in the End.

Obtaining
Purpur blocks and pillars can be mined using any pickaxe. If mined without a pickaxe, it will drop nothing.

Natural generation
Purpur blocks and pillars can be found naturally as part of the structure of end cities.

Usage
Purpur blocks and pillars are primarily decorative blocks, similar to other brick-type blocks. They can also be used to craft different variants of the block.

Trivia

 * Purpur is the word for a specific shade of purple in multiple languages, including Swedish, German and Cornish (and French pourpre to a certain extent).
