I found the crusader parked right next to the evil eye prisoner room on lvl 2. The evil eye prisoner room is the room number 3 at the eqatlas site.
He dropped the ******* sword on first kill. Was easy to take down. Pulled eye and got him too, killed both with another lvl 30.
I'm sure there would be a lot more adds at a lower lvl so the ease of this might have had to due with the fact that we only had to fight things that conned lght blue or better and they are not that many on the 2nd floor who do at 30.
