Every aspect of the quest was tough. The mobs never got the memo about to-hit and armor class! They just dont care what AC you have they will beat you up with every swing. As anyone who has run the quest on EE knows the boss is a beast. I felt like a fly playing chicken with a Mac truck. Probably the hardest part of the end fight was when the fire reavers spawned. I hit them with EIN and EVERY one of them saved! Not sure whats up with that but took me about five minutes of running around fighting and healing to take them out.
Main stratergy against the boss was to keep my HP full and keep damage on him as much as possible. My reflex save was high enough to be no fail on the spikes when he reverse gravity so that wasnt a big deal.
Not the toughest solo I've done but was lotsa fun.
