Su-hyeun... you're an idiot. You knew for a fact it was a lich, and knew you could get one surprise hit in and you aimed for his useless neck? That thing he ain't got when you damn well knew the crystal in his head is an insta kill? So instead of efficiently popping the crystal and calling it a day, you will now have a long, drawn out fight where any npc death makes him stronger? Idiot. And you kept going on and on about how you needed to be quick?! Double idiot.
