Minecraft Dungeons:Heart of Ender

The Heart of Ender is the final boss of the main story of Minecraft Dungeons. It appears in the Obsidian Pinnacle after defeating the Arch-Illager. It is the last boss in the main game, not counting the DLC or the Mooshroom Monstrosity.

Lore
After the Arch-Illager is defeated, he is sucked towards the Orb of Dominance, which transforms into the Heart of Ender. It has an unnatural power, the likes of which have never been seen.

After the Heart of Ender is defeated, it leaves a trail of black liquid reminiscent of an End Portal, leading to Archie and the Orb, which is back in its original form. Then the players destroy the Orb, freeing Archie of its control, who celebrates its destruction with the players.

Behavior
The Heart of Ender has 3 different attacks, used in an order. It uses a powerful target attack to strike the player's attack. Between attacks, it "crawls" around the arena, leaving a black trail of limited size behind it, which damages players on contact.

Note: The attack names are conjectural; an official name has not been released.

The Heart of Ender leans back and spits out a cluster of small pink fireballs from its mouth. When a fireball touches the ground, it explodes in a small radius, leaving behind pink flames that damage players on contact.
 * Fireballs

The Heart of Ender raises up and fires 4 pink beams from its stomach in a plus formation. The beams then spin around, dealing massive damage on contact.
 * Beam Loop

The Heart of Ender sinks into the ground, before unattackable heads in its likeness rise out of the ground facing different directions, each firing a pink beam from its mouth before sinking back into the ground. Once all the heads have started firing, the Heart of Ender rises out of the ground, and the attack pattern repeats.

Drops

 * Wonderful Wheat
 * Great Hammer
 * Slayer Crossbow
 * Lightning Rod
 * Ember Robe

Trivia

 * The Heart of Ender is called "Arch Visage" in some of the game files
 * The Heart of Ender has similar eyes to an Enderman.
 * It is assumed that the Orb of Dominance, rather than Archie himself, transforms into the Heart of Ender because not only is Archie still visible after the transformation (and the Orb is not), but several creatures summoned by the Orb like the Jungle Abomination have similar eyes.
