Hello Ownedcore exploring community. Today i was exploring Azjol-Nerub and came up with this. It was not as easy it seems. I failed 5 times total there are some DC zones including water and invisible walls on the way down. I think it's possible to use this way to get to other parts of Azjol-Nerub which i couldn't myself do since the drop is pretty straight down. Enjoy the Video.
As for the wall that i used warlock abilities to get inside other ways are:
1. Puntable Marmot (worked 3 times for me)
2. Puntable Marmot + charge ability.
3. Warlock way with eye of kilrogg placing the portal inside the wall and teleporting there.
