[LOTR] What are Galadriel's powers?

Does Galadriel have some kind of magical powers, or are those caused by her wearing one of the three elven rings? 

I'm mainly talking about the stuff she did at Dol Guldur when fighting Sauron and in Lothlrien when talking to Frodo about the ring.

Magic doesn't really work in Middle Earth the same way it works in other universes. Most of her power is keeping Lothorien from fading and her people from declining faster. She can will nature in a way, but nothing like casting fireballs from her hands.
