Well we didn't have any such events in our mountain run, so the only thing we had to worry about was not being sniped by wolves that come from behind before you have a chance to block. The mini-dragons were easy, and the golems (or whatever they are called) were easy to kite, so we didn't find it as difficult as the swamps where just one hit from an ooze was enough to kill at least my character, and where you were slowed down by the water, falling into deep water and having all your weapons/shields de-equipped etc etc.

I don't think my small group will continue honestly, because now I've read up a bit on the game and it seems like the grind will be even worse going up to iron and beyond. The copper/tin-grind is already really ♥♥♥♥♥♥♥ long and dull for me.
