Precipice described him as having been a pretty formidable mercenary when he was younger, so I don't think it was much of a stretch. He had also been training a lot before the show down when Zett was over confident because he felt Quinn would be an easy fight. I think that voctory was more Zett's loss than Quinn's win.
