Ender Dragon

Ender Dragons are 7 different variants of Boss summoned with Summoning Eyes in the Dragon's Nest. They drop powerful loot including Dragon Armors and Dragon Fragments when killed.

The Ender Dragon has 7 variants: Protector, Wise, Unstable, Superior, Strong, Young, and Old.

Summoning
The Ender Dragon is summoned with 8 Summoning Eyes. These eyes must be placed in the altar in the center of the nest. After all 8 are placed, the dragon is summoned and the fight will begin. This is similar to the summoning of Arachne with Arachne's Keeper Fragments.

Variants
The Ender Dragon will spawn as one of seven variants. The dragon variant affects the Dragon's health, behavior, drops, and attacks.

The Dragon Fight
After 8 Summoning Eyes have been placed, there will be a brief period before the dragon will hatch from an egg in the sky, knocking all players a large distance away from the Dragon Altar at the center of the Dragon's Nest. After the dragon has spawned, the dragon variant will be announced in the chat.

The door to the Dragon's Nest will shut, the gaps at the top will be covered with glass and Ender Crystals will spawn around the nest on top of obsidian spikes. These crystals must be destroyed to stop the dragon from regenerating health. Destroying a crystal rewards its destroyer with. Destroyed crystals will respawn after a certain amount of time.

Additionally, Gregory the Opportunist will spawn near the Dragon's Gate. He will sell a Decent Bow as well as Arrows at a higher price than the Weaponsmith in town.

Attacks
The dragon has three attacks, which all deal True Damage.
 * 1) Rush - The dragon will charge a player, inflicting heavy damage and knockback.
 * 2) Fireball - The dragon will fly to a point in the arena, stop in place, then fire a barrage of fireballs at players. These fireballs explode and can damage multiple players at once. They will knock players high up into the air.
 * 3) Lightning - The dragon will briefly stop in place, summoning lightning around it and creating audible thunder sounds. After a brief period, it will summon lightning and smite players from above. This attack can be avoided if the player has a block above their head.

After some time has passed, the dragon will summon groups of Zealots. These Zealots are immediately hostile, even if the player has not damaged or looked at them. The Dragon also makes already existing Zealots hostile.

When players are killed, they must make their way down to the Dragon's Nest again, and break down the sealed door. The door has lots of health, can be attacked with both ranged and melee attacks and will open again when its health bar is depleted. Both endermites and endermen spawn as the door takes damage. This can be avoided by using a horse pet to glitch in or using the Dragon's Nest Travel Scroll.

After the Ender Dragon is defeated, Gregory will depart and hostile mobs will not spawn in the Dragon's Nest for a brief amount of time. All existing mobs within the Nest, including Special Zealots, Voidgloom Seraphim, and Necromancy mobs, will instantly despawn. During this time, dragons cannot be summoned. After this brief time has passed, a message in the chat will announce the respawning of the Dragon Egg, after which mobs will spawn as normal and players are able to summon another dragon.

Drops
Each player that damages the Ender Dragon will receive individual loot, including Ender Pearls and Enchanted Ender Pearls.

Major loot received is governed by Dragon Weight , which determines a player's eligibility for major loot. Note that achieving a weight requirement does not guarantee the respective drop.

Dragon Weight is determined in the following manner: Dealing the final blow also gives +50 weight.

While players will be ranked in damage regardless of whether they damaged the dragon, they must deal damage to the dragon to receive Dragon Weight.

Players will only receive one major loot item from a dragon. Reaching the weight requirement for an item grants eligibility to receive it, but does not guarantee it will drop. Items are rolled in the order shown by the loot table, meaning the player has a chance at receiving the item of the highest weight requirement they achieved first, followed by items after it in descending order.

Every Summoning Eye placed will increase the chances of obtaining an Aspect of the Dragons and Ender Dragon Pet.

The drop chance of the pet is 0.04% with  and 4 Summoning Eyes placed.

Dragon Scale, Dragon Claw, Dragon Horn, Aspect of the Dragons, and Ender Dragon Pet all have a chance to drop when reached 450 Dragon Weight. Dragon Scale, Dragon Claw, Dragon Horn, and Ender Dragon Pet won't subtract the weight when drop looted.

Players will receive a Dragon Fragment for every 22 remaining Dragon Weight after the weight of the item they received is subtracted from their total weight.

Players will achieve a minimum of three fragments if they dealt at least one damage.

Trivia

 * Similar the Magma Cube Boss, players will see their ranking for how much damage they dealt to the boss.
 * The Ender Dragon was the second Boss added to the game.
 * There is currently a bug in which in certain lobbies, summoned dragons will disappear after a player hits it with the Aspect of the Dragons ability. The boss bar and Gregory the Opportunist is still present, but the dragon itself is missing. Ender Crystals still spawn around a minute after the disappearance, and it stays like that until the lobby resets.
 * Ender Crystals will stop spawning after a few minutes if the Ender Dragon still has not been killed.
 * When a Dragon is defeated, mobs, including Voidgloom Seraphim, in the lower areas of the Void Sepulture (between layers 10 and 26) will also be despawned.
 * The Old Dragon has the 6th highest health of all non-dungeon mobs, at . This is second only to the Arachne tier 2 and Minos Inquisitor.
 * Holy Dragons do not exist, even though Holy Dragon Armor, Holy Fragments, and Holy Lost Adventurers do.
 * Sarite has killed the most dragons in the game totaling over 31,000 dragon kills as of 10/26/21. However, dragon kills were not counted unless you got the final blow until the bestiary update.
