Haven't finalized but assume this build will do well. You will need a flame to cast but im assuming you'd forgo Gravelord sword and swap it or figure out equip load. With high crit, a bit of DoT, ability to parry, Fire whip for range cheese, dance and combust for close quarter and finally a fair amount of poise it seems this build is fairly well rounded and suits a playstyle that is fishing for crits and heavy attacks.
