Well I beat it finally... I used GRE, Pharoah, 2 AOF and green droid. It took about 30 minutes... and all day leading up to this lineup. I wasted about 6 troopers on the search for this team.
Pharaoh Eddie equipped with guard and shell was necessary to survive round 1 (the hardest part IMO), my AOF had strike/invisibility equipped, which was also very helpful. Thanks to Kkkreg5 for using his AOF.
I did make it to the boss with SSD, assassin NBOL and green druid, but I spent about 15 minutes trying to take out the damn shield, and never did so I started over with the winning lineup.
Now to figure out what to do with these immortality talisman... I need an assassin Eddie... Time to farm PVP for eternal frags I guess.
