Dark Eruption was the most powerful Force attack that could be accomplished when using the Dark Side of the Force. It could only be used by the most powerful Sith. To use it, the Sith would have to forget about everything around them and concentrate fully on the Force. It also consisted of specialized breathing techniques and letting the Force flow through them. Once this was done, the person would have to put all of their power and strength into the move. It would then create a black ball of Force energy. Depending on where and how it was directed by the Sith, it could destroy armies of thousands, ships, and even planets.
