I was the poster who made the comment about it making her 50% stronger too ... the point here is that she should not be strong enough without some enhancement to do all the things she did ... this is why I don't accept the "Gasp" as evidence that she cut Aran'gar off from the Power, ... she would have needed the angreal to do that IMO ... this I base on an entire series of hearing that men are stronger than women and that it's harder to shield someone of the opposite sex ... the list goes on ... even IF Graendal was stronger than Aran'gar it's not likely that she's enough stronger to have been able to shield her and Delana and make a Gateway without the angreal since even Nynaeve under less stressful circumstances could not slam a shield on Elayne who is obviously weaker.

As for the sensing a shield, who is to say what someone with as much OP knowledge as the AOL Channelers have can sense? We learned tons of new information about the TP in the same chapter ... we have no indication that Aran'gar couldn't sense that she had been shielded.

We know that the angreal she possessed is amongst the weakest in the series, but have no indication of what it really offered. Another poster commented that Graendal's assessment of the angreal indicates that it must be weak enough to not seem like an enhancement ... I disagree with that, but it's why I phrased the above the way I did.

If that angreal added a 50% lift to her natural strength and she did in fact use it I can believe that she could cut Aran'gar and Delana off and weave the gateway. But without the angreal I find that scenario ridiculous.
