I simply left my character awake all night the night before, and when I attempted the raid again last night, it was easy! My character fell right to sleep like a baby before the crack of midnight, this is a huge breakthrough for my gameplay! I look forward to the bonuses my character will carry throughout the day after having a full night of sleep.
On another note, I was finally able to replace the curtains that Belnik, my imp so foolishly burned. If only I could get him to behave as well as Nheeroon. Felhunters have such an even temperament.
