I wonder why nobody ever ask this question.

I can't fathom what it does but it must be something he only uses for extreme emergencies ( not to say that the situation in York New wasn't a serious emergency). I think if the plot goes back to Kurapika, Togashi should reveal it. and the people I could really see him using this against are Nobunaga, Phinks, Feitan or Chrollo.

What do you guys think it does?
