Lung-Killing is you killing at least one lung before dealing much damage to the boss, ensuring you never have to deal with Deep breath. Therefore there are two main strategies for dealing with the lungs: Lung-killing and Lung-Mitigation. If you don’t, your team will be cleaved down in no time from the gigantic damage output, unless your damage output is so incredibly high that you can outpace him. Each turn he will pump up one or both lungs to this effect, and you will need to be able to hit both rank 1 and rank 4 to stop him from using Exhalation. The Seething Sigh’s strategy is to pump his lungs up with air and then to mitigate or disrupt the team so that you can’t stop him from using Sundering Exhalation. On combo, target takes 3 stress and is knocked back 2 ranks. Deals 4-6 damage at 10 crit, deals 100% more damage if target has combo (so if you guard him the guarding unit will only take 4-6). 1 turn cooldownĭying Light: Targets any hero with Combo. Applies weak and shuffles, and may deal stress. Hysteria: Targets 1 hero, or 2 if at least 1 lung is dead. Applies combo if Sigh’s HP is under 50% (140 or less). 1 turn cooldownīlind Rage: Targets any hero, Deals 4-7 damage at 10 crit. Deals 2-4 damage at 20 crit, and 2 stress and 3 burn. Wrath and Rancor: Targets any 1 hero, or 2 if at least one lung is dead. If both lungs have tokens at that point, deals 20-30 and 3 stress instead. Deals 10-20 damage at 5 crit to everyone, and 2 stress. Sundering Exhalation: Used as a free action if one or both lungs is filled with air at Round end. These raw numbers (presumably) change if he has higher max HP from Loathing attacks, but the percentages stay the same. Sigh will only start using Deep Breath at 70% HP (196), and will use it with higher likelihood up until it reaches 30% HP (84), at which point it will always use it. If the lung takes 6% of its max HP in damage (12 for front, 9 for back), it loses this token. One/both Lungs get filled with air, which is shown by a token. Shallow/Deep Breath: Free action at Round Start. The Seething Sigh Darkest Dungeon 2 Act 2 Boss Guide Moveset

They are not immune to Debuffs, though only Vuln can do anything to the lungs. They are immune to DoTs, Stuns, and Move effects, though these wouldn’t do anything anyway (apparently DoT will if you somehow apply it).

The front lung has 200 HP, and the back lung has 150 HP.

280 Max HP, 5 Speed, Perfect Move resist and immobilize, and 2 turns per round, not counting its free actions.
