I don't even remember fighting Blue Smelter and the number of posts about it has me concerned

I haven't played the DLC since my first playthrough all the way back in 2017 and I do not remember Blue Smelter whatsoever. Gearing up for Return to Drangleic the number of posts I'm seeing about Blue Smelter is concerning me. Did I never fight him? Did I unga bunga my way through back in the days where I didn't understand ADP? Did I somehow cheese it with poison arrows despite it not looking like it should be possible (it is, quite easily at that), or maybe just summon through it?

Was I just good at Dark Souls?? (lmao no, I never beat Fume Knight)

Make it make sense and fill in my Swiss cheese memory holes
