i don't like the claw. its a bad gimmick weapon used by bad nerds. anyway thorn hands boost all fist-weapon damage by ~10% so they're good to have. dwgr is the more obvious ring choice but if you're comfortable swapping to hornet quickly it's worth doing before a pivot. if nothing else the claw is good at baiting backstabs out of bad players. make use of your pyro and the rolling r1 to bait siderolls and roll backstabs. you're prolly better off attuning another combustion pyro instead of flash sweat but i like to have it around and people don't tend to expect it. something interesting i've heard but haven't seen tested is that black flame/great combustion combo into the basic combustion. if so, it's good to keep in mind as well
swap claw for estoc for fallback turtle (and prolly grass crest for dragoncrest or plain crest)
