ok heres one its very handy i hope its not a duplicate
for the grim collector quest you need to kill skeltons right
well while farming them i discoverd this:
in the ROS (ruins of sorrow) in the main entry yard of the south entrance skeletons spawn inside the houses and tend to stand next to the walls u can target these with the nearest taget action and kill them more times than not they dont fight back the catch being on some occasions u cant use your skills but u dont really need em if it cant fight you

by doing this i saved hours of downtime and thing was noone noticed what i was doing and ive never seen anyone else do it
ok thats all i have for now plz plz say its worth it a very nice tip in my opinion
