It is usually tough where just start entering the 2nd part of broken valley. Try build up some level by killing mob around. Bout those skeletons outside lovis tower, I approach them when having roughly level equal to their level. There is 2 entrance to lovis tower, one which require a lot climbing. I usually climb up to higher area and kill those skeleton below with bow 1 by 1. Pretty easy like that. Just think of any tactics or way which you can use. It shouldnt be too hard after all.
