Here is a rough video I did today:

It is surprisingly difficult to get a full run due to people coming in and out of Sebilis. I don't want to interrupt them by trying to dissuade them from going through.
At the end of the video Bbeta and his group came in to finish up one of the tri-mobs hehe.
Might be best to just do the first 8 mobs, since I did those without incident. That is entrance to the bottom of the stairs. I kill the 8th mob at the 37 minute mark in the video.
I also died at the end of the video. I got a bit too greedy and used a runway that was too short. I should have used Dooming Darkness lol.
