Description

End Crystal is both a naturally generated structure element and a craftable item, making it one of the few blocks with an active combat role. Groups of them appear on top of each obsidian pillar around the central fountain in The End, where they continuously regenerate the Ender Dragon's health while a beam connects them. Destroying all crystals before fighting the dragon cuts off that healing entirely.

Players craft one from a glass bottle, an eye of ender, and a ghast tear in a specific arrangement. Placing four around the central exit fountain respawns the Ender Dragon for a repeat battle. The item also activates a Respawn Anchor in the Nether. When struck by projectile or melee, an End Crystal detonates with an explosion similar in power and radius to TNT — dangerous in close combat and useful as a trap component in adventure maps and defensive builds.
