Shaman.

Valerian and Fortuna were moving in the direction of the tent. They both had their unique style of fighting. While Valerian was engaged in close-range fights, Fortuna was akin to a death god from the skies. 

She would dive down and cast spells while breathing fire on the enemies. As a dragon, her damage output was off the charts. In the same amount of time as Valerian killed one enemy, Fortuna would bring down too. However, at most Fortuna had always injured her targets seriously, leaving them wailing on the ground. 

Priscilla was observing this oddity and was confused, she thought if only she could talk to someone knowledgeable. However, she did not understand bird language and her bonded companion beast was lying inside the beast pouch. 

Dejectedly she took back her gaze. Unknown to the point that Valerian was also asking the same question to the dragon on the ground. He let out a low growl and asked, 'Why are you not killing them?'
