Cumulus vex

From Dragon Quest Wiki

The Cumulus Vex is a recurring monster in the Dragon Quest series, first appearing as a boss in Dragon Quest VII. It is a king of the skies whose body is made up of clouds.


Cumulus vex has the appearance of an old wizard whose body and clothes are completely composed of golden clouds. It has solid green eyes, pointed ears, and a long majestic beard that reaches down to its feet. On top of its head, it has two long strands of "hair" that stick up like horns while the rest seems to blend in with the billowing robes it is wearing. Its hands have three digits each and the bottom of its body is surrounded by grey stormclouds. It is a fearsome enemy to face in battle, calling upon razor-sharp blasts of wind that rip apart its enemies and overwhelming the unprepared with sheer numbers due to its ability to call upon sky fries to aid it in battle. In the Nintendo 3DS version, it speaks in wind-based puns. Although the cumulus vex was a boss in its first appearance, it went on to become a regular enemy when it reappeared in IX.

The Cumulus vex is a tough boss, being able to attack twice in one turn. It uses wind-based attacks like Thin Air, that hits all of the party for about ~60HP, and Wind Sickles, that hits one party member for ~80HP (~100 in the 3DS version). Its ability to summon multiple sky fries makes the battle more difficult. Thankfully, sky fries can be put to sleep, have their spells sealed away, or confused to take them out of the action.

Attacks that hit more than one enemy are very helpful. The Flame Boomerang that can be purchased in Aeolus Vale is also helpful because it hits all enemies with decreasing damage. Boom is effective as well. Unfortunately, Ruff's Call of the Wild and the Shepherd's Lambpede are completely useless in the battle. Physical attackers should focus their attacks on the Cumulus vex or use Sword Dance. Spellcasters should keep the party healed, cast Kabuff and Oomph when necessary, and use group attack spells to defeat the sky fries. Magic Barrier can also be cast to help protect the party, but in the 3DS version, it no longer reduces the damage taken from its wind attacks.

Make sure that you keep your party's health is above ~100HP and that you are sufficiently buffed to achieve victory.

Cumulus vex is named after cumulus clouds, a type of cloud with a puffy white base that often leads to other types of clouds due to several factors and the English verb vex, which means to annoy or irritate.
