This is my analysis on the battle, based on the limited knowledge we bear of these 2 characters: Both are on-par in lightsaber combat, as Baras I believe has stalemated satele shan, and defeated Darth Angral (correct me if i'm wrong), and Freedon Nadd has fought on-par with his master, Matta Tremayne, whilst he was a jedi knight, and has killed many jedi with his bronze blade. Tremayne was considered a master lightsaber duelist. In terms of the force, Freedon Nadd was an accomplished sith sorcerer, and his sorcery was taught to darth zannah through his holocron, the sorcery zannah used in the form of covering herself and others in a false light side aura, driving people insane by showing them their greatest fears, or even simply masking her presence in the Force were all within the scope of her abilities. This would suggest Nadd also had mastery over these abilities as well. The only force ability I can think of that baras has ever used is force lightning, which was easily blocked by the wrath. Nadd most likely gets the edge here. As for an overall fight, they would fight on par in lightsaber combat, but nadd's sorcery, specifically his dark healing and insanity abilities, would prove too much for baras to handle. this isn't even factoring in nadd's sith magic-enhanced blaster. I declare Freedon Nadd the winner.
