Notes from author
For mid/late game invasions. Perfect SL to invade Tomb of Giants, New Londo, Izalith and even Anal Londo. Just as good as any SL125 Quality, really.
You could even bring the SL down by removing 3 points in Vitality and go for lighter backup weapons as well as the regular Knight set to reduce the Endurance.
That's a build you could make without ever going in NG+ and that's nice.
