galadriel ring of power
Galadriel is described by Tolkien as having the power to perceive the desires and motivations in the hearts of others. In the film this is interpreted as being telepathic. She had the power to heal, create, protect and preserve although some of these powers were either due to or greatly enhanced by her possession of the Elfstone and Nenya, a ring of power. After the War of the Ring, Galadriel is described as casting down the walls of Dol Guldur and cleansing the Mirkwood. Technically this would be after the destruction of the ring and so would be after Nenya's power failed and gives us a good idea of Galadriel's innate power.
