#5 Dont leave after you've died a few times.
#6 Dont worry about repair bills, because in the long run it costs more to take him out stretched over weeks of time. If you're out of money, ask to borrow some. If he's downed in ONE-NIGHT, it will be plenty cheaper for everyone in the long run.
#7 Love thy Raid-leader; this is a fight that RLs in many guilds get very frustrated in. It's not just their job to "keep the peace" and keep the raid nice 'n loose and having fun, it's everyone's. If people ARENT having fun? See #5.

#8 Maintain the "inchworm on a straight razor" attitude. Lithe and flexible, yet sharp and efficient. You must come with pwnage on your mind and not be willing to waver until you succeed... this goes for RLs too.
About #8, it's really what this fight is all about. Your mind. If you're weak of it, u die repeatedly and quit; you're of the type that plays
WoW solely because u can spam one button and get pretty purple gear... If this is you, DONT SIGN UP.
