There are some mines you can disarm with mechanical skill. But it appears others that you can't. Not sure how to deal with them.
Once, they just didn't go off. That was odd. They had on a previous play, and they did when I restored a save, but one time they didn't.
The only approach I'm seeing currently is set off a mine, take a lot of damage, go back to town and heal, repeat. That seems sketchy.
Without spoilers much, any ideas?
