Calasmos is the true evil behind the events of Dragon Quest XI: Echoes of an Elusive Age, and serves as the game's final boss in the third act of the game. An ancient evil known as the Dark One, he once attempted to cover the world in darkness long ago.


Calasmos first appears as a black Tockle with a small nebula in the center of its body, being the form its soul was ensnared in after its temporary defeat by Erdwin several centuries before the game's story. In his true form, Calasmos is a colossal, humanoid insect whose green exoskeleton is pitted with small craters that betray his otherworldly origin. The connective tissue at the joints is blue, and the head is infantile and almost perfectly round. Calasmos has no neck to speak of, with its head being ensconced by its armor.

The monster's precise height is unknown and varies slightly between the HD, 3DS, and 2D versions of the game but easily towers over the main cast. The upper torso is bulky and fitted with six small orbs over an oval center gem. The arms are as long as the main body and terminate into different appendages, with the right being a three-pronged claw with an inorganic nozzle and the left ending in a digitless stump possessing six bullet chamber-esque opening from which projectiles are fired. The lower torso is made up of overlapping armor plates that rattle with the creature's movements, and the legs are undersized for the hulking body.

Calasmos' personality is one of almighty contempt for beings that dwell in the light, and it seeks to eradicate all life on the planet.


Calasmos is a being of alien origin to the planet Erdrea, who did battle with Yggdragon untold years ago. Though victorious in the clash, this act would sow the seeds of its own ruin as Yggdragon became Yggdrasil.

Years later, it was confronted by powerful resistance in the form of Erdwin and his companions, and Calasmos was defeated in the Gallopolis desert. It was at this time that the monster revealed the depths of its cunning, stalling its demise by whispering promises of power and glory to Morcant and corrupting the wizard to stab Erdwin in the back before the final blow could be delivered. Though Morcant, now Mordegon, would prove to be a thorn in Calasmos' side in the future, the manipulation proved successful and the allowed it to escape the sealing of its body in Erdwin's Lantern.

During the short-lived reign of Mordegon in the second act of the game, Calasmos journeys to the now-descending Lantern to merge with its original body, but it is destroyed by Mordegon before it can complete the required incantation to start the process. Calasmos' Tockle form collapses to it's knees in despair and remains motionless after these events, with only a long line of ellipses being displayed when it is spoken to.

Though confronted with a tremendous setback, Calasmos trails the Luminary when he discovers the Tower of Lost Time. Calasmos manages to defy the rule preventing more than one person from being brought back and secretly travels with the Luminary as he rewrites time. Calasmos consistently prevents Mordegon from touching the Sword of Light, driving the demon sorcerer's patience to its limits and causing him to abandon subtlety and reveal himself. After his death, Erdwin's Lantern descends and Calasmos makes his way to the desert once more. This time he successfully regains his original body while declaring that all life would be destroyed.

Afterwards, he gestates inside the Lantern, now in the form of a dark star, until he's confronted by the Luminary.

One popular favorite strategy for defeating Calasmos is bringing the Luminary, Erik, Veronica, and someone who can poison, like Sylvando, to exploit Erik's Victimiser skill to deal 600% damage. Apply Oomphle when possible and have Erik use his Divide skill for a total of 1,800% damage.

Alternatively, Veronica and Serena and use their Mighty Magic Burst pep power to deal up to 5994 damage in one turn. This will leave both girls spent until MP restoring items are used. To optimize the Mighty Magic Burst strategy, pep both twins before the battle starts by any means necessary, and make sure every party member on the frontline (including the 2 characters not participating in the nuking) carry at least 1 Elfin elixir and at least 1 Pep Pop(it must be a Pep Pop and not a Pep Pip). Use the Sword of Light to dispel the damage-halving effect on Calasmos. Use Mighty Magic Burst at the first possible opportunity afterwards. On the next 3 actions you get (regardless of who gets these actions), use Elfin elixirs on the twins followed by a Pep Pop to pep both twins at once (note that you can delay these actions in order to heal as needed). Both twins should be at max MP and pepped. Use another cast of Mighty Magic Burst at the first possible opportunity, and as long as the twins' combined MP equals or exceeds 1834 (meaning Mighty Magic Burst deals 5502 or more damage), Calasmos will be dead.
