Ender Crystal

The Ender Crystal is an object found in the end. They only spawn during Ender Dragon boss fights to gradually heal the dragon. They will respawn a certain amount of time after being destroyed. Destroying them will cause them to drop a Crystal Fragment, which is used to craft the Catalyst and the Crystal Armor.
