Sadly Ravens manipulations backfire on he rbadly althoug she made them evil she also amped up their powers greatly and because of that they rebel against. (Good durability showing for raven though taking multiple amped blasts from satrfire anwhos normal blasts hurt Wonder Woman)
In Our Worlds at War, why was Raven wearing a white turbin? I've read somewhere that her powers were multiplied. Just curios, because she was able to channel the power of all the Amazons, and Tempsest to Darkseid. I've never seen her pull any feats of that magnitude. before. I was very impressed.
Ok, so, Darkseid, in a depowered state, had Wonder Woman tap into the minds and souls of the Amazons through the wonderdome. She asked them to focus their beliefs into one unified energy and then Raven gathered the energy and funneled it into Darseid so he could regain power. We also witness some telepathic communication between Diana and Raven. I'm not sure what context lies behind Raven's power levels, but as far as I know its just a high showing of her standard powerset.
