"What the hell, why do all the bosses lately have a second phase?!" Shadow curses as he looks at the Dullahan that was enveloped in green fire, the monster grows a bit before stopping at the height of 2.2 meters.
"I'm sorry to disappoint you and your friends but this isn't really something you would call a phase 2," Aethion speaks to Reign with a serious voice suddenly.
"What?"
"It's a small evolution," Aethion continues, "You have managed to deal a lot of damage to the Dullahan, not to mention you managed to make his fire almost useless. As Dullahan's are of a higher grade of undead they do have some intelligence, he probably realized that the only way he could win is if he can improve his soul flame, and by allowing it to consume the horse that had become useless he achieved so."
