The second change to Fenrir is that the Devouring ability of Fenrir has now extended to the internal energy of prey. This way, he won't use energy stones or Cloudy Date Metac to cultivate. He can always increase his cultivation by devouring the cultivation of others.
The third change is that Fenrir can produce more Tracking marks now. This means that he can track and hunt more than one prey at the same time now.
The final, but not the least important change to Fenrir is that after it consumed his main energy chamber, it awakened a fifth ability. This ability is the Siphon Ability. It is an alternative ability to the Seal Ability.
The Seal Ability can only take effect once the target dies, but the Siphon Ability can take effect when the target is alive. And through the Siphon Ability, he can devour the internal energy of the target while they are still alive.
