End Crystal

An End Crystal is a unique entity in Minecraft, primarily found on the main island of the End dimension. They are typically located on bedrock atop obsidian pillars and serve as the main healing source for the Ender Dragon. End Crystals can be placed on obsidian or bedrock, and they explode instantly when attacked or damaged in most ways. The explosion is powerful, similar to a charged creeper. End Crystals not only heal the Ender Dragon but can also be used to respawn it. Placing four End Crystals around the End portal will resurrect the Ender Dragon. Additionally, End Crystals have other uses, such as being used for traps or as decorative blocks. There are two forms of End Crystals: one with a base, usually generated by game mechanics or by commands; and the other without a base, placed manually by players on obsidian or bedrock. End Crystals fire a healing beam at the Ender Dragon, and the beam's direction can be modified with commands to mark locations or objects. Despite having multiple uses in the game, their primary function remains as a healing and respawning tool for the Ender Dragon.
