It is preferred to use Чун Юнь as a Взрыв стихии Nuke over Main DPS as his Обычная атака scalings are very low, even when including [C1]. His Взрыв стихии on the other hand hits extremely hard on later constellations and takes a much higher total damage portion over his Обычная атака. On top of that, you can Reverse Таяние all 3 hits of his Взрыв стихии on enemies applied with strong Пиро, such as Беннет's Элементальный навык and Взрыв стихии.

At [C2], his Элементальный навык reduces ability cooldown that is cast within the zone by 15%. This is one of the few abilities in the game that can reduce cooldown.

Чун Юнь's Взрыв стихии is calculated as Claymore damage, which means it breaks Гео Structures / Shields at a much easier rate and can proc Shatter.
