For the most part, the Dalish mage never delivered the final blow (he had always been uncomfortable with taking a life, even in a circumstance such as this), but left enough weakness on the enemies that whoever did kill a target wouldn't have to sacrifice much energy or time to do so.
Amidst all the shouts and grunts of the group and their darkspawn attackers, the Dalish mage moved back and forth between the area of the battle, shifting places frequently and quickly to make sure that he wasn't targeted as a sitting duck while he was casting his spells, most of which were simple enough that he wasn't left drained after casting them and therefore was able to move around efficiently. Being distracted by Conlan's apparent "battle strategy" (this was something that would be addressed later, the disapproving look Faer caught on Ordhan made that evident), the darkspawn took their attention to his companions instead of him, something that Faer had taken to his advantage by utilizing the fact that he remained almost entirely unnoticed.
This advantage, however, was snatched away when Faer locked eyes with one of the smaller darkspawn (a grunt, judging from the Warden Commander's descriptions) as it hissed and growled at the Dalish elf, almost as if it was trying to scare him. His keeper had told him many old stories about darkspawn came to be, foul and evil they were, but also servants of their master, said to not have their own mind and corrupted without given a choice. The Dalish mage had learned of their history and, as a result, had pitied them, wondering how he would feel if his entire life's purpose was to destroy and kill without his own freedom, all in the name of an Old God, otherwise a figment of their imagination aside from dragons who claimed themselves as such (and if they weren't Old Gods, would the darkspawn know the difference?)
But now, as he stood in front of this creature and could see it's revolting and putrid features, horrified by it's animosity and repulsive presence, that empathetic feeling immediately dissolved and was left with a sense of pure hatred and disgust. Was this the effect that darkspawn had on everything the creatures encounter? Were his companions also filled with such dislike that a venomous urge to gash the grunt's head open with his staff chilled up his spine?
Faer almost felt sorry for feeling such an immediate reaction to the creatures. Almost.
The grunt geared up it's bow, positioning an arrow and was aiming to shoot at the Dalish mage as Faer did the same, the shimmer of magic revolving around him with his eyes closed as he shot it with a paralysis spell, freezing that particular darkspawn in place before the creature could finish aiming. There was no time wasted between the next attacks, two hits from his staff and the grunt fell to the ground, dead.
Getting ready to pinpoint another target, it became apparent to the Dalish elf that the battle was nearing an end -- to be expected, considering the numbers were evenly made, but the group was obviously superior in fighting skills -- as the last couple of darkspawn were given the final blow and the group had received a victory in their first battle with the darkspawn. Unlike his other companions whom were given scratches from the skirmish and heavy blows between their armor, Faer was left unscathed saved for the small amount of fatigue that was left from the adrenaline that was now draining him. He scanned the group to make sure that everyone had been alright, caught sight of a newcomer (an elf, perhaps Dalish considering this was the Brecilian Forest) and that Conlan had been bitten by one of the darkspawn.
He turned to the nearest healer, Hissra, and requested with a tired voice, "You can perform a healing spell on him?"
Not waiting for an answer, urgent to make sure that no one else had been fatally wounded or was dead, he then called out, "Is everyone alright? Any injuries that need immediate attention?"
