Adhara declared loudly without a hint of fear in her eyes, she blatantly said that to Azzen's face.
Humanity believed that the Shapeshifter was the most witted out of the Supernatural races since they can shapeshift into anything and definitely relies on trickery, but Adhara has learned through her own experience that it was not the Shapeshifter that rely the most on trickery.
It was the Demons instead, even though they were the last race that needs to rely on trickery.
Since demons were considered a battle race as their numbers can be replenished through unknown methods, they doesn't need to use trickery. If they wanted to, they can fight a number game sending demon after demon into the battle.
Knowing that it's logical to think that they don't need to use trickery in their fight.
