Trying to make a dragon-based build, claws and flames and all.
The single Claw is used as the main weapon for bleed damage and also poison if the Rotten Pine Resin is used as back-up.
The Notched Whip is used as a back-up way to build-up bleed as its off-hand attack is fairly quick.
The Dragon King Greataxe is mostly a why-the-heck-not weapon than anything, and the pyromancy is to emulate a dragon breathing fire.
Have fun.
