You don't fight Nex during any quests, so if you wish to fight her you have to enter the ancient prison in GWD, which requires 70 strength, constitution, ranged, and agility since you need the frozen key pieces. As for the boss fight itself, you pretty much need the best or close to the best gear available.
AFK, dang that's a lot of requirements, plus a daunting boss fight in and of itself. No wonder your concerns for being able to defeat Nex in the first place for a chance at the Nex defender o_O

Oh, so I wonder why this person back in 2011 said the quest is hard and really wanted my main to level prayer to do it? I thought there was a fight?? Hmmm
