Only thing is Kirito's swords has around 150 more atk than olive and blue rose and blue rose and olive has around 150 more strength than Kirito's swords. So are there any difference between str and atk? Cause you can also increase +5 str and atk when you +19 your equipment but if one gives more than the other it would be good to know.
