If you can't run hard mode (and I imagine, most people are in guild that can't), it can be completed by sneaking in. Rogues can do it in hide, other classes likely can use invis potions. Once you get there, the active point has a cast time timer, so be careful. It takes you out of hide, and there are some mobs are going back and forth near it. I was able to do it from inside boss room.
Quest completion opens up at least two more quests.
-- Rustyx --- 92R / 92S / 92M on Reni (Guild KnightShift). Yes, running the new FOTM R/M, cause I am not elf enough to be WD/S.
Oh, and people who have more than 3 classes are clinically insane.
