I played on master, and just yesterday, since I started playing on 11.11.11, I played thru the mainquest. I'm level 46, and Skuldafn ruins was perhaps the first time in this game when I'm about to scream like pre-pubascent brat.

The moment I arrive I'm greeted by 6-8 deathlords and 3 dragons and numerous scourges and wights. I manage to kill the scourges (which I hate ALOT more than deathlords), wights and around 3 deathlords before I had enough and run up to the temple, avoiding yet more deathlords with bows. The temple interior was a cake compared to the previous and took less tries to get to the roof/portal. This time it's an elder dragon, frost dragon and a normal dragon instead of 3 normal dragons (??) and even more deathlords. So I used full storm call shout and go turtle mode (found a nice man-sized hole in the wall) and shield charged deathlords into their doom while trying to survive the dragons. To my luck, the storm call's lightings managed to evaporate Nahkriin, so I ran like hell, grapped his mask and the staff and ran some more, activated the portal - off to Sovngarde, bye and f**k you!

So how was your second major last battle in the game?

I played this part a few days ago with my Khajiit, and it was difficult. I died at least three times thanks to those Deathlords.
