While doing missions, Klaus noticed something he hadn't noticed before. Somehow, indirectly, he now seemed to be able to use positive energy during the night.
While not directly and only using his new ability, he could understand that, at least, it was possible to use both energies at the same time, and with that, he ruled out the possibility that the positive energy in his body had spoiled his main ability.
Although he had seen both energies moving inside his body before and did not seem to mind the presence of the other, seeing them inside was different from seeing them materialized in front of him, functioning equally.
Originally, he thought he couldn't use that ability at night, so knowing that he can is a good sign.
Thus, he spent most of the night doing quests. During his long night of hunting, he encountered different beasts that were a bit unusual.
