The main factor that enabled such a crazy clear was the use of creative game mechanics to boost the damage of the Corruption ability 暮光毁灭
, which unlike many other Corruptions, scales exclusively from your maximum health.
What made such massive Twilight Devastation hits possible was the stacking of the minor tank Azerite Essence 勇卫之力
, which increases the health of all Tanks at the raid by 3%, stacking with itself. With all 30 tanks in the raid using the Azerite Essence, plus many Stamina-increased items, many of the tanks of the run were stacking millions of health, and by proxy, dealing millions of damage every time they got a Twilight Devastation proc. They were also requiring other items such as 生命充能的泰坦裂片
equipped, to try to fish for as many Twilight Devastation procs as they can get.
