I guess I didn't see this as much of an asspull because 1) we know about Nen after death and 2) there was a precedent: Gon and his fight with Pitou. Didn't Hisoka just basically do the same thing Gon did? As in, he made a huge, last-resort contract with his Nen. At the same time, like other people in this thread have said, how come there was no sacrifice? Hisoka seems just fine(well, except for his missing limbs, now covered up); hell, Hisoka looks even stronger now. I'm surprised there was no consequence to his actions, like with Gon.
All that being said, unpredictable outcome to the battle, as to be expected of Togashi. And Hisoka is so savage he managed to take out two Spiders right after coming back to life. Crazy shit. RIP Shalnark and Kortopi. We barely even knew anything about Kortopi. lol
Shalnark may have been able to put up more of a fight had Chrollo not taken his ability, but it is what it is.
And just like that, Togashi connects this otherwise out-of-nowhere fight to the Dark Continent arc, since the troupe(or what's left of them) is heading to the ship. This arc is going to be insane. And now that Hisoka is targeting the troupe one-by-one, I can see this pissing off Kurapika, since Kurapika's revenge is basically his reason for living. But hey, maybe they'll team up.
I'm going to be sad if Hisoka kills Shizuku. She's too cute to die... :(
Anyway, Chrollo won the battle, but it looks like Hisoka will win the war.
