The Seething Sigh

The Seething Sigh is a boss with three separate attack targets - the right lung, the left lung, and the core. In orderto win the fight, you will need to kill the core.However, ignoring the lungs entirely will allow the boss to use a devastating attack called Sundering Exhalation.

Many of this boss' attacks stackStress, but you might also seeBurn,Weakness, andBlindnesstokens being applied to your Heroes. The damage output of The Seething Sigh is not too difficult to tank, which is good because it is quite tanky itself.

DoTs are not very useful in this fight due to the boss' high resistance and the fact that neither the right nor left lung takes any turns on which to apply the DoT damage.

The Seething Sigh has seven total abilities. Each, apart from Sundering Exhalation, is focused on disrupting your ability to attack the lungs in a timely fashion.
