I think the most important thing to take from this chapter is... the fact that Hisoka is crazy. We may have forgotten that, as he has appeared in lots of arcs, some times as ally, where he has been "reduced" to someone who happens to love to fight strong opponents. No, no, he always was nuts, as this chapter remind us with who we are dealing. He is the Joker of HxH.
What he does when he resurrects? He laughs and say "oops fighting Chrollo in those conditions was a bit too much ♣. Reality sure how to give you a wake up call! ♥". He was close of saying "me so baka! >_<"
He is offered help to heal his wounds and disfigured face and he chooses to be a zombie like mesh of nen and flesh for life. And then he goes out prancing and happy as if nothing happened.
Did Chrollo have help form the RG members in the fight? I opt over the "yes" side. There are clues like that panel with Hisoka's comment of the fishing line (when the Black Voice's antenna mysteriously disappear). The fight ended and that little mystery seemed to amount to nothing, but this chapter reminded me of a nen user specialized in similar "fishing lines" threads, Machi! What was the point of that panel, if not to give a clue of what was really happening? Narratively speaking, it served no other purpose. The other point that seemed suspect is when Hisoka (which despite losing this fight clearly he is around Chrollo's level) estimated 30 more clones, and then 200 attack them. If Korotopi was doing clones and Chrollo just using the stamp and seals he would produces the clones much faster than acting alone.
Finally, the three RG members were in the building as they quickly recovered the body to be sure he was dead.
Obviously the fact Hisoka's crazy gambit worked is... Togashi. To make it work, it was needed that his body wasn't very damaged (he really die by suffocation), and then Machi happens to join head and neck, and for his nen after death work, and then Togashi played loose with things like brain's oxygen deprivation. It feels a bill bullshit, and mainly because nen is supposed to survive after death in rare cases, usually associated with great grudges (a bit like the idea in fiction that spirits staying on the world after death if there is a big grudge still pending). It didn't feel like Hisoka has a great grudge, he was more "oh well I'm going to try this..."
I wonder if, given how nen conditions/pledges work, Hisoka has received a boost because he limited himself to not fix his hand and foot and not look for help, so the nen used to replace them is stronger than normal.
About if Hisoka killed the spider members because they didn't have powers in that moment, we don't know. Chrollo may had returned them back, releasing them from the book, but in Shalnark's case the phone is physical object so that's why Chrollo asked if he wanted it now. I think the main cause Hisoka had an easy time with them was the pure surprise factor (combined with the fact they didn't know Hisoka's new plan). If you aren't someone like a strong enhancer, who gets to give the first hist is very important.
