good roll dodging is key to this boss. if you get your agility to 96 that should help on that front.So I'm stuck on smelter demon.. Any ideas? I am SL 99 vit 24 end 22 start 22 Dex 30 str 30 I am a physical build most likely going for str beyond this point to lvl 120
using flash sweat, small orange burrs, flame quartz ring and alonne knight/captain sets should soften the blow should you get hit. just get some resin from vengarl and punish his 3 hit combos after you dodge. when he does the flame core use a lifegem after taking some damage and stay close; it should counteract the constant damage.
otherwise, as legend said, you could just go through the room that had the flame inside of it and go up the ladders to skip him. you'll miss the ring of blades +1 and smelter specific stuff as well as a bonfire checkpoint.
