Skoll is sinking father beneath the ground while Hati is being blasted by attacks from every angle. The two lesser fenrirs are no longer in control as they are being overpowered by the domains that are active. The worst part for the two lesser fenrirs is that they do not have their own domain skills.
A Domain skill is one of the qualifications to attain godhood which means not all boss monsters would have it. If the two lesser fenrirs evolved themselves then they might awaken one since fenrirs are godlike monsters as long as they are not bound.
The two lesser fenrirs finally reconnected their minds back together. Hati, who is basically almost at death's door, told his sister that his time is almost up. He would have to use the unregulated energy that he had accumulated.
