It's the last one my friends and i need for the meta... we really want the keg.... but ugh! It's so hard to get.
I'm not sure what we're doing wrong. We've ran it 30+ times. Every time we make sure, SURE, that no fire is getting anywhere. We fight the boss away from the village and make sure he is never facing it.
We usually split up and go to the North, the docks/bridge, and the Ancient passage. Nothing EVER gets close to the city...
We've tried other things too, just to see if SOMETHING would activate it, but we're just not getting it.
Also, I heard you were supposed to interrupt Fire Line, but it's got that Shield Symbol around it that says it is un-interruptable? What's with that?
