During the battle, she was in a secret room that she had created in the Tower's Dream Shadow giving orders. She created an illusion weave to make one of the Black Ajah look like her. Then she captured Egwene by surprise attack and brought her to the secret holding area. She really didn't do much nor was anything she did that impressive. I liked the scene personally, but let me know if you could indicate something that she did that was so powerful and beyond the scope of the other Forsaken we've seen fight in the dreamworld. It just seemed to me that she hung out, swooped in to take her prey to her secret place and then got beat at her own game.

That's my point - Moghedien uses her willpower to avoid detection, and this is what enables her to gather so much information. We also saw her rip Birgitte from the Dream, but in general, the way she uses T'A'R fits her nature - she wants to hide and would rather initiate a surprise attack and vanish than stay and fight. My point boils down to the fact that Moghedien doesn't want to fight at all preferring an easy victory by subterfuge so fighting her is different.

I think Moghedien used that term because your belief in them bound your will to make them act the way they did in the real world. Being "bound" by an a'dam, for example, made Moghedien immediately think she couldn't channel and rather than marshal the willpower to defeat it as Egwene did, she simply gave up.
