End Crystal

An Ender Crystal is an entity found in The End.

Natural generation
Ender crystals are found atop the many obsidian pillars in the End.

Usage
The Ender Crystal entity is not solid and can be walked through freely. An Ender Dragon will pass through the crystal with impunity.

The healing beam is neither obstructed nor is its power diminished by entities or blocks.

Ender Crystals can be pushed by pistons, but doing so in order to align them with a block causes them to explode. They also explode if they are pushed to a burning block. If they do not explode, they will be set on fire, to no effect.

When hit by the player, they will explode, leaving only bedrock and the pillar. The base appears to be made of bedrock, with a crystal hovering over it and fire engulfing it. The player must destroy a majority of these in the immediate area in order to defeat the Ender Dragon effectively. If you destroy an Ender Crystal while the Ender Dragon is recharging from it, the dragon will take a small amount of damage. The ender crystal can be destroyed by hitting it with any projectile, like snowballs and eggs (except splash potions, fireworks and bottles o'enchanting).

The Ender Crystal's explosion is 50% more powerful than TNT. No wall can stop an Ender Crystal explosion reaching another crystal in range, and a chain reaction of Ender Crystal explosions is instantaneous.

Their primary purpose is to recharge the health of the Ender Dragon, who will charge from the nearest crystal within a small radius. An Ender Crystal can heal multiple Ender Dragons at the same time.

Trivia

 * Placing water above one using a bucket will cause a looping effect, where the fire is continuously put out and reinitialized as the water attempts to flow down and is stopped. The water will not spread, as it can flow downward, but is prevented by the reoccurring fire instantly taking its place.
 * Despite having only 1 health, Ender Crystals do not appear to be damaged by fire.
 * Oftentimes, the fire will stay after an Ender Crystal blows up.
