The Draugr Boss and Lowering the Bridge

You encounter this boss around a corner in a fairly tight cave. You won't be able to strafe him easily sideways so I decided to strafe in and out of the reach of his sword to avoid getting hit by him. There is plenty of space behind you to retreat and heal yourself with magic. Once you have killed this boss you will run into a raised bridge and an obvious lever to pull. That one will only cause spikes to come out of the side of the wall. Instead whilst standing next to that lever and looking at the raised bridge turn around 180 degrees and you will see a second lever that will lower the bridge.
