Darkest Dungeon 2 - Seething Sigh
Me beating the Seething Sigh on the 3rd attempt. I used more or less the same party composition on the 2nd attempt and it was going decently well until the hellion missed the back lung with her iron swan move, after which everything immediately fell apart.
The hero paths used are:
Hellion - Ravager
Man at Arms - Sergeant
Grave Robber - Deadeye
Plague Doctor - Surgeon
