Oli spent most of a sun getting accustomed to the minute, gradual changes his dark essence was experiencing. Zelsh's advice was the core of Oli's cultivation.
"The change won't come overnight. You must apply these changes gradually and steadily, or you'll stunt your affinity for death essence. Consider every step of the Mortal Championship as a learning experience. That way, by the time you reach the final round, the change will be complete."
The change was also guaranteed thanks to the Toxic-shadow Clan. They had long made two versions of the Dark Abyss Technique, one with dark essence and one with death essence. Oli had already switched to the death essence version and could focus most of his attention on absorbing cores.
