Hell/Hell difficulty and Diablo drop

Ok, I went through Hell/Hell mode with my Mage, and I had a lot less trouble than when I did the caves. The death knights didn't hit me that often (AC only 281) and the biggest trouble i had was the effreets were immune to fire/lightning. The unique mobs weren't that tough (especially Diablo) although they did drop some nice stuff I couldn't use...

anyway.

Also. The three times I went through (one for each difficulty) Diablo always dropped the same item, the unique saber Nightflange. Not a bad item, but he always dropped it and only it. Grr....
