Scents are close to impossible to sense. They are one of those awareness that can easily bypass and even trick one's senses.
One intriguing instance of a magic attack transformed into a scent was how Deception's Illusion ensnared Kyran during the war in the Ylfaen Kingdom.
With her using one's sense of smell as her Illusion's trigger, it was nearly impossible for Kyran to defend against it, especially if it was scentless, once it infiltrated his system. His Void magic was adept at countering magic attacks that could cause status effects because they were still made of magic energy and could easily be detected. However, defending against an attack that influenced one's sense of smell was still challenging.
The reason was simple: by the time the Void magic energy circulating in his body found any trace of magic energy that triggered his sense of smell, his brain would have already registered the scent's effect and fallen victim to it.
