Not very difficult, but there are some small puzzles to this level. Once you figure out the basic premise (go up, then around and across through the middle, then up, around, across through the middle...etc) you shouldn't have a problem. The only hard part is Durza himself. The tactic I used was to let Brom get in close to fight him and stand back using quick arrow shots (just hold right trigger to target and keep tapping A ), then using your new fire magic any time it's ready (pull the left trigger and hit B). When he shields himself, run around him in circles to avoid the blades and continue with the previous tactic. Takes a long time, but it's effective.
