The higher the level of existence, the less likely it is to see the so-called "berserk mode" often depicted in novels and TV shows. Gods are no exception. At this level, every ounce of power requires painstaking effort to accumulate and cannot simply erupt in bursts.

The same principle applied to Diana. Though she appeared to be growing stronger under the shroud of hatred, forcing Boris, a god with three divine authorities, into retreat and leaving him defenseless, the truth was far simpler: Boris had been holding back, unwilling to counterattack due to her status.
