Martial arts skills in this game get more and more powerful the more they're used. The last attack of a martial arts weapon are far more powerful than the first attack. The problem with Lynn is that while she has solid enough stats, both times she's joined the party she had no chance to use up those martial arts weapons to the point where they'd be effective. It should be noted that enemy abilities with identical names are normal attacks without this progressive increase in power.
