I did my solo necro promo without dying which took about 2 hrs and lots of save / reload. Basically ad nausea. But I pulled it off.
Also got GM Water - waterwalk spell + invisibility scroll and the rest was easy as I townportalled my way out of plane of water. Getting to the teacher was not as easy though but when invisibility ran off I just climb the mountains in straight line to save time and bypass the monsters.
Now I have to grab Master Air so drain Balthazar Lair and then back to DWI to complete all the quests.
Btw, I also have Master Learning and Master Meditation. Master Dark and Expert Air.
