Minecraft Dungeons:Ancient Guardian

The Ancient Guardian is the final boss of the Hidden Depths DLC. It spawns in the Abyssal Monument.

Appearance
The Ancient Guardian is an oversized elder guardian with a predominantly dark purple body as well as three pink stripes. All of its spikes are a light purple to white gradient, and its eye is pink in color with a white iris. On its back are a few patches of algae, coral and seaweed, with some on its tail. A shard of the Orb of Dominance is lodged in front of the algae. Its face is full of cracks and a long scratch is seen across its eye.

Story
The Ancient Guardian was previously an elder guardian who lived in the ocean monument where the story of the Hidden Depths DLC unfolds. After the shattering of the Orb of Dominance, one of it’s shards landed within the hidden depths of a deep ocean. Sometime after, an elder guardian discovered the shard and unwillingly become corrupted by it. The shard rapidly transformed the elder guardian and began to spread it’s corruption to a nearby ravine, enraging the ocean currents. At the time that the heroes begin to descend the ocean depths, the corruption of the ancient guardian begins spreading throughout a coral reef, wreaking havoc on the nearby small islands.

Upon reaching the end of the lower monument, the ancient guardian is seen destroying it’s own lair to challenge the heroes who dare to enter the chamber. After an intense battle, they manage to defeat the ancient guardian, calming the ocean currents.

Behavior
When the hero reaches the arena, the ancient guardian enters by bursting through a wall. After taking notable damage, it can swim away from the arena to avoid further damage. In addition, it has five attacks:

The ancient guardian can attack nearby heroes or summons by piercing them with its spikes, which creates a high-damage shockwave.
 * Spike attack

The ancient guardian will sometimes pop out its spikes as a means of defence. Attacking it with a melee weapon will result in the attacker taking some damage back in a similar manner to the Thorns enchantment.
 * Spike Protection

The ancient guardian is capable of firing a yellow beam at it’s target, which behaves the same way as its weaker counter parts but deals more damage. After doing this attack, the guardian retracts it’s spikes, and can be attacked without suffering thorns damage.
 * Laser attack

The ancient guardian can summon guardians to assist itself during battle. It usually summons about three guardians near a hero, but this attack sometimes spawns an elder guardian instead. It cannot spawn anymore elder guardians if there is already one alive.
 * Summon minions

Biomine
Every so often, the ancient guardian comes into the arena and summons a number of guardian-shaped non-attackable mobs that explode shortly afterward, though it cancels this attack after becoming sufficiently damaged. When the biomines explode, they leave behind a temporary poison cloud that deals continuous damage to nearby heroes or summons.
