Disruptive Wave (previously DeMagic, originally Freezing Waves) is a recurring skill in the Dragon Quest game series series. Introduced in Dragon Quest III as a monster-exclusive attack, it nullifies all stat changes, such as those caused by buffs (Kabuff, Oomph) and debuffs (Kasap, Deceleratle). It also removes all bad effects cast on you by the enemy, therefore, sometimes a double edged sword.
It is typically known by major bosses and is practically required on final bosses, making the use of stat changing moves futile in such battles if one's luck is unrelentingly bad.
Used by Zoma.
In the remakes, Disruptive Wave is one of the special abilities that Psaro can learn.
Used by most of the later story bosses, starting with Dhoulmagus.
It is worth noting that Disruptive Wave acts slightly different in this installment as it now only affects the opposition. This makes debuffs viable against many bosses since they can't use the ability to clear them away. The player can now use this ability against opponents, provided they invest at least 42 skill points in the sage's "Enlightenment" skill tree. This ability only costs 10 MP to cast.
Disruptive wave also destroys all tension boosts.
A Powerful Spell reducing all stats to 0
Can be obtained from a few high-level skillsets, particularly exclusive sets such as Nimzo. It functions identically to IX. Its worth noting however that another skill "Wave of Relief" is the other half of this skill, instead affecting allies only.
Works identically to how it did in Joker, however, it now has its own usage as a trait which can be used by very high rank monsters such as Nimzo or Leonyx. The trait will cast the titualr spell at the start of any turn randomly and does not take up a move. This can be incredibly frustrating however as the monster will cast it at random; making any team including one of these very ineffective at using deuffs; especisally as AI very rarely uses buffs in the first place and using Sap is practically manditory for scouting the tough monsters.
Monsters will cast the spell if the have the trait no matter what; which can be annoying as it wastes time, particularly with Nimzo who has a very long animation for its usage.
One particular note is that Rigor Mortis; the final boss starts the battle with a bounce effect that inexplicably cannot be removed with the spell.
