Although there was no hesitation for Quinn when he had selected the option to activate his soul weapon, now that his body was in the middle of a strange transformation, he did have a lot of worries on his mind.
Unlike the last soul weapon Quinn had used, he was able to test its uses and figure out how best and when to use it. Testing was extremely helpful due to the large drawback Quinn's item type soul weapon had. If his enhancement type soul weapon also had a similar drawback, he would be finding out about it during the fight.
Not just the drawbacks, everything about the soul weapon he would have to try to find on the job, learning how to use it and what it could do. All while fighting one of the strongest enemies he had ever faced. Of course, this would make anyone a little nervous.
