Sinthuja: Maybe this will help someone who struggles with useless pugs doing this achievement.
Main problem with this encounter is to stay alive until Saboteur Kip’tilak reaches 70% health and triggers all bombs. Sabotage hits fairly hard so you want to keep dodging healing abilities and use Stampede + 5 x spirit mend combo at some part to survive. Also you want to avoid causing domino effect and explode too many bombs with saboteur or you will end up killing yourself or failing the achievement. Good side is you don’t have to defeat him to get the achievement.
