'''Disruptive Wave''' is a recurring skill in the ''[[Dragon Quest (series)|Dragon Quest]]'' series. Introduced in ''[[Dragon Quest III]]'' as a monster-exclusive attack, it nullifies all stat changes, such as those caused by buff abilities such as [[Kabuff]] and [[Oomph]], debuffs such as [[Kasap]] and [[Deceleratle]], and [[Tension]].

It is typically known by major bosses and is almost always used by the final bosses, making the use of stat changing moves futile in such battles if one's luck is unrelentingly bad. 
==Appearances==
==={{DQ3}}===
Used by [[Zoma]], as well as some of the superbosses such as [[Xenlon]] and [[Gran Dragon]].

==={{DQ4}}===
Disruptive Wave is a technique used by enemies such as [[Estark]], [[Psaro the Manslayer]], and [[Aamon]]. However, the [[Hero (Dragon Quest IV)|hero]] can unleash this by using the [[Zenithian sword]] as a tool in battle.

In the remakes, Disruptive Wave is one of the special abilities that [[Psaro (Character)|Psaro]] can learn.

==={{DQ5}}===
Disruptive Wave is learned by recruited [[King slime (recruit)|king slime]]s at level 18. [[Saber]] can also learn it at level 33. As in Dragon Quest IV, the Zenithian sword can unleash this effect if used as a tool in battle.

[[King Korol]], [[Grandmaster Nimzo]] and [[Estark]] can use Disruptive Wave in their boss fights.

==={{DQ6}}===
Disruptive Wave can be learned by any character in the [[Hero (vocation)|Hero]] vocation when they reach rank 2. This is the only way to learn the ability, as the Sword of Ramias instead casts Oomph when used as an item in battle.

As far as bosses go, [[Dhuran]], [[Mortamor]] and [[Nokturnus]] have access to Disruptive Wave.

==={{DQ7}}===
Learned via the Hero vocation as in ''VI'', but also by reaching rank 6 of the [[Druid]] vocation in the PSX version and rank 3 in the 3DS, or rank 7 of the Paladin vocation in the 3DS version only. It is superior (and cheaper) than [[The Great Leveller]] as it covers more effects.

==={{DQ8}}===
Disruptive Wave is used by most of the later story bosses, starting with [[Dhoulmagus]].

==={{DQ9}}===
Disruptive Wave is learned with 42 skill points allocated into [[List of enlightenment skills in Dragon Quest IX|Enlightenment skill]]. It costs 10MP to perform.

It is worth noting that Disruptive Wave acts slightly different in this installment as it now only affects the opposition when used by a character or a monster. This makes debuffs viable against many bosses since they can't use the ability to clear them away. This isn't used as heavily by the story bosses (only [[King Godwyn]] and [[Corvus]] uses it). However, several of the grotto bosses and ''all'' of the [[legacy boss]]es will use this ability.

==={{DQ10}}===
[[Sage]]s learn an ability similar to Disruptive Wave called [[Clear Your Mind]], by investing 100 points into their Enlightenment skill. It costs 10 MP to cast, and blasts a wave in a cone in front of them, removing positive status effects of any enemy hit. Demon Swordsmen can learn Disruptive Wave with 70 points invested into their Wave skill. It costs 6 MP to cast, and functions similarly to Clear Your Mind. Several boss-level enemies also use this skill in battle.

==={{DQ11}}===
Disruptive Wave is used by late-game bosses.

===''[[Dragon Quest Monsters]]''===
Called DeMagic in this game, it requires the monster to reach level 20 with 100 MP and 140 intelligence. It is naturally learned by [[DeathMore]] (Final form),[[Mirudraas]] (Transformed) and [[Zoma]]. It can also be learned by monsters with [[Surge]] and [[Ultradown | UltraDown]].

===''[[Dragon Quest Monsters 2]]''===
DeMagic now requires 252 intelligence to learn. It is naturally learned by [[PsychoPiz]], [[Orgodemir]] (Transformed) and [[Warubou]].

===''[[Dragon Quest Monsters: Caravan Heart]]''===
{{Stub}}
===''[[Dragon Quest Monsters: Joker]]''===
Disruptive Wave can be learned from various skill trees.

* [[Cleanser]] (100 points)
* [[Cursader]] (60 points)
* [[Dhoulmagus (skill) | Dhoulmagus]] (34 points)
* [[Diamagon (skill) | Diamagon III]] (30 points)
* [[Estark (skill) | Estark]] (100 points)
* [[Mortamor (skill) | Mortamor]] (100 points)
* [[Nimzo (skill) | Nimzo]] (100 points)
* [[Rhapthorne (skill) | Rhapthorne II]] (51 points)

==={{DQMJ2}}===
Disruptive Wave can no longer be learned from [[Cursader]], and [[Rhapthorne (skill) | Rhapthorne II]] now only requires 44 points.

{{clear}}

===''[[Dragon Quest Heroes: The World Tree's Woe and the Blight Below]]''===
[[Psaro (Character)|Psaro]] can learn the ability when he joins for 8 skill points, and the skill only strips buffs from its targets instead of all stat modifiers. It costs 8 MP to use. He will also use it against the player in the battle against him. Additionally, [[Tension]] is not reduced when used.

==Trivia==
*The {{Translation|Japanese name|いてつくはどう|Itetsukuhadou|"Freezing Waves"}} refers to Zoma's ice magic, as he was the first to use the skill.
*In the initial English version of ''Dragon Quest VIII'', it was referred to as a '''Wave of Ice''', a literal translation of its Japanese name. Subsequent releases, such as the [[cell phone]] and [[Nintendo 3DS]] versions, have changed it to Disruptive Wave.
