Just check the mine? No. When we see something suspicious? Sure, we can check it out. And we won't get any reward for such a failure, as you described. And Imelda might even faint from it. I'm for going to the mine. Will we wipe out? Well, it happens. Otherwise, we'll be running away from every red quest. Siv, we've found something that has a good chance of being a key event. If we mess it up, we'll mess up the quest. Your suggestion is the same as saying we should skip the patrol. So, I'm for going to the mine stealthily.
A suggestion from someone with a bonus on new fate maps and support from someone who might not be sent into the mines because of their agility, heh... But nevertheless./
