Hi me and a couple of people have found a solution to this problem but its not simple sadly. 1. You need 6 people, i'm guessing it can be done with 3 people (2 if you are not including yourself) but it will be more difficult. 2. 4 people (2 fights) need to to be in the wrong obstacle arena at the same time (it seems that runescape has changed the default/first selection of obstacle area for fighting) 3. While the 4 people are in the wrong arena the person who needs the clue needs needs to start an obstacle arena fight then they should be in the northern (correct) arena Obviously it will be difficult to either find 5 friends that are all free at the same time. So I suggest that you join a treasure trail help friends chat I used "TT Help" and it seems that world 40 is the ideal world for this if there is less then 6 people taking part. Good Luck and I hope this helped :)
