Hmm. If Hisoka needs more clues, a whole trail of them, Chrollo doesn't mind laying them out. He reaches for a pocket on the inside of his jacket, slipping out that little black book with the red handprint at its cover, eyes still on Hisoka and smile still in place.

"I think it would depend on what information you asked for." Because there's some information that he plans to give out either way. "But as long as we're talking about information, maybe you could also explain your abilities to me?"

Requirements one and two, laid bare. If Hisoka wants to go as far as the third one to see if Chrollo's ability is really restored, well, he'd be more than welcome to it.
