During a phase the boss will apply a detrimental effect (debuff) called "Aetherochemical Bomb" which should deal AoE damage not damaging the debuffed target (not sure about that but it should be like that) applying also paralysis in the AoE if the debuff explodes near a mine.

Steps:
1. Cast The Warden's Paean by BRD to everyone or to some targets including self.
2. The boss will eventually apply the debuff on a target.
3. The debuff will not be prevented by The Warden's Paean when applied.

"The Warden's Paean" should nullify every detrimental effect dispellable by the Esuna or Leeches spell.
The first week of Heavensward, The Warden's Paean couldn't prevent the Pacification effect after the Berserk of WAR, then it got fixed and now if you apply The Warden's Paean to a warrior with Berserk, the Pacification will be dispelled at the exact moment the Berserk effect finishes

I hope I was clear. ISP and PC specs are pretty much irrelevant since it's something it should happen independently by my configurations.
