I’m in Chapter 4 with Hugo and I’m trying to get some Thunder Runes from the Sirens in the Cyndar Ruins (The ones inside Ancient Highway). It’s a über-rare drop and I want several of 'em, so obviously I need to use the Hunter.
Problem is I have no clue as to how to do this. Up to now I was putting enemies to sleep and then hitting them, but the Sirens are immune to that. Is there any other method that besides waiting for the 5% chance hit?
