Notes from author
Managed to distribute his stats in a way that he could have his NG+ Vitality, and still being able to keep a relatively low level for mini-maxing, with a decent attack rating from Grant (roughly 850 damage on the skeletons, which is around the same damage his phantom does on NG).
I think it's pretty much impossible to make him as OP as he is on NG+ and beyond, even maxing out all stats to 99...
Oh, also managed to keep his physical defenses and resistances on par with what the FuturePress's Official Dark Souls Strategy Guide says.
Have fun cosplaying as Paladin Leeeroooy Jeeenkins!
