Yeah, it's easy to solo if you get the map online, in fact I'd say it's much easier and faster to solo it unless you wanna get some xp in the process.
Flee seems to be really helpful for just running past the Aw'zdei or whatever they are called and teleport up, but since you have Sleep as COR they wont be hard to control anyway.
I solo'd all my key items (and got all the Quasi for the map) in one day, so just getting the key items for the fight should be fast. Just take the north entrance to the elevator when you are going for the Brands (and the BC) and you should be able to avoid detection without much problems.
Just remember to carry reraise just in case (at least on your first try getting through the gauntlet), and if you get spotted just die by the door (to the elevator) so you can reraise when the pots return to their places and the door opens again.
