I recently found myself going to the kalros ri because I needed COPPER. When I got there I was astounded by the amount of spiders in the upper caves. I'm not kidding you, I was being attacked every 10s by these creatures. This made me never want to go to ri with a set again... So my proposal is to turn down the mob spawns on those things and also decrease their spidey senses because they target you from miles away.
