Nightmare Spiritual Mark

Krune flew through the forest, alert of his surroundings, knowing very well the range of the nightmare effect around a Nightmare Demon Wolf. In fact, it ranged around twenty meters. Beyond that, the effect only made someone faintly drowsy. 

Even when the number of Nightmare Demon Wolves in a pack increased in number, the range never increased. Of course, the potency of the drowsiness subjected beyond the range of the nightmares also increased.

Nevertheless, this was also the perfect indicator of a Nightmare Demon Wolf's presence. 

Of course, Krune didn't rely on something as dangerous as that, simply chasing after the sounds as he maintained an alert state, intending to swiftly fly away the moment it felt like he would fall into a nightmare.
