Not only did the Abyssal Dragon have a terrifying five hundred million health points, but it also possessed an incredibly high defense, which if not for Shen Xinya, it would have disabled most of the earlier attacks. Furthermore, as a dragon, the Abyssal Dragon regenerated its health at much higher rates than the other races as its vitality was countless times higher.
Dragons were known not only for their terrifying physical bodies, but were also known to be geniuses at controlling magic and mana; therefore, the Abyssal Dragon's magic spells were undoubtedly devastating.
