Once he has confirmation from Drake, he nods, and he slowly starts channeling.

At first, the aura isn't too bad. It's similar to the one that was present in the fight against Falcon. A creeping feeling that death is here and you should run. It is by no means trivial, but people used to life-or-death scenarios, like most Persona users, can readily handle it.

But as the aura grows and grows in strength, its nature starts shifting. It starts becoming a very strong you will die right now feeling. It starts being about the terror of certain, inevitable death. There are creeping thoughts in those within the aura's influence that unless they run away in terror right now, they will die. It requires great mental fortitude to recognize these thoughts as foreign and manage to push them aside.
