So, I'm like the 3rd person I know to solo this on Ghallanda and one of them was at lvl cap 16. However. I have been attempting this elite and tonight got so close. I had never completed this solo on any difficulty so I went in on normal just so I can say I've solo'd it as well! Got a video of it but I'm not giving up on the elite abbot solo so I'll hold off on posting it for now. Been having some issues posting lately, apologize for that.
Here is the video, I was going to restart after first death on tile but decided to keep going. It's a very messy run but my first Abbot solo all the same.
