Obviously, this is a build that does not use a shield. Mainly because I rarely find myself using one when I have it, and so it can use two different catalysts in the left hand (I've gotten so attuned to it that putting a catalyst in my right hand just slows me down and makes me vulnerable to screw ups). I have a Lightning Estoc for the reason that In my own opinion it looks cooler than Chaos. It's also for emergency use for GMB users since the GS of Artorias gets its damage almost halved due to its default magic damage (Nothing against GMB). I've been having trouble with Moonlight GS bumper humpers recently so I added GMB for these situations and other ones if I run into them.
Good luck guys!
