Ender Crystal Sprite
Ender Crystals are enchanted crystals that appear in The End. These crystals will restore the Ender Dragon's health, so it is advised to destroy them as soon as possible. Ender Crystals are exclusive to The End, so you will not find them anywhere else. It is impossible to obtain an Ender Crystal (not even with Too Many Items, Creative Mode, or the /give command) without the use of mods or server plugins.
