Lore
The ancient guardian, as its name implies, is the oldest guardian of the ocean monument. After the shattering of the Orb of Dominance, one of its shards landed within the hidden depths, corrupting the ancient guardian.
With its newfound power, the ancient guardian was emboldened and empowered, turning from a brilliant white to a corrosive purple. The shard of the Orb of Dominance attempted to use it to spread its corruption, but it was bested by heroes journeying the ocean's depths.
Spawning
In the Abyssal Monument, the ancient guardian has a unique spawning cinematic where it breaks through a wall in the structure.
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:
Spike attack
The ancient guardian can attack nearby heroes or summons by piercing them with its spikes, which creates a high-damage shockwave.
Spike protection
The ancient guardian sometimes pops out its spikes as a means of defense. Attacking it with a melee weapon results in the attacker taking some damage back in a similar manner to the Thorns enchantment.
Laser attack
The ancient guardian is capable of firing a yellow beam at its target, which behaves the same way as its weaker counter parts but deals more damage. After doing this attack, the ancient guardian retracts its spikes, and can be attacked without suffering thorns damage.
Summon minions
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 elder guardians if there already is one alive.
Summon biomines
The ancient guardian spawns 3-5 biomines that explode shortly afterward, although 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.

A biomine is a type of guardian-shaped mob that the ancient guardian summons every so often when coming back into the arena.
Behavior
When summoned, biomines 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.
