What the hell is going on
Chrollo's abilities are complicated as fukk
This person gave a explaination
So he can replicate himself using Gallery Fake to create an inanimate version of himself, marking it with Sun and Moon on the book and left hand. This will allow the clone to detonate the bomb by shifting the book between hands.
Swap his appearance with the clone with Convert Hands, generating a clone with no Sun and Moon, and an original with fake Sun and Moon. Chrollo never specified if clones get Arrow Marks here.
Bookmarking Convert Hands, he opens the book to Order Stamp to animate the clone, and gives it the order "Kill Hisoka", because the Kill command causes the puppet to take on its original personality.
Weakness: Chrollo must keep the book open to Order Stamp while bookmarking Convert Hands. This means he cannot go for the kill with Black Voice, and the book is open making it blatantly obvious.
The key is that Convert Hands replicates appearance of whole body, in other words the fake Chrollo will have a book. As a result Hisoka will perceive two Chrollos with open books and arrows. But he will see that one has a bomb marking on his hand, and immediately assume its the clone
Now the finisher. Obviously there is "Invisible Bomb - Get Rekt" but that is what you call a boring ending.
Chrollo clone swaps the book to his left behind a puppet, and holds it for a bit as he goes for a rush. Simultaneously, Chrollo opens the page to Order Stamp and transfers the bookmark to Black Voice. Because of the way Chrollo holds his book, it won't be possible to see Sun and Moon about to detonate. This is further heightened by the fact that the clone can hide behind audience puppets. Hisoka is caught in the blast shockwave, but obviously escapes unharmed. However, he was caught offguard. In this moment, the real Chrollo closes the gap ad tags him with Black Voice
