Can someone explain in detail how you are suppose to do it? I always fail on it because they see me...Do i need to be on higher level? They are lvl 50 so i don't think it matters...I have been able to get to the place where I'm suppose to put the sleeping powder in but failed afterwards. But now i can't get there anymore and I've tested alot of times. Please explain with details of how i should do it because i won't understand otherwise xD
