Do sneak attacks increase sneak xp, or just give u 2x damage?
I think sneak levels based off the damage you inflict with sneak attacks also but don't quote me on that. Either way you get a good chunk of skill xp from attacks. Or at least so my bow sneak attacks tell me, melee is probably a different story.
Never lower the difficulty, fight like a man and use hide and run tactics.
Not possible. He refuses to leave the chamber, as does the draugr he spawns with, until he's taken about 10% damage (which takes 3 or 4 Fire Breath shouts) then he chases me down and its not exactly a large area you get to backtrack.
For an easy win, kill all the additional Draugr. Fus Ro Dah the spectral guy, beat the crap out of him when he's down, run away, repeat.
I didn't check but he's probably weak to fire since he casts ice spells and his chamber is littered with 'resist fire' potions.
Easier said than done. The Draugr Scourge he's in the room with has that much health that I can barely do 20% damage before the boss is beating my head in again. And weakness to fire means jack when you're a lvl19 Sword + Shield warrior. I'll give it a few more attempts, seeing if I can just spam the crap out of shield bash with adren rush to keep him staggered, otherwise I'll lower it to Adept and see how it goes.
Its generally fine other than the odd mini boss. Creatures are seriously overpowered atm as most seem to be able to 2-4 shot me (I'm talking sabre cats and bears, not Giants and Mammoths) so hopefully that'll change when I get stronger armour (because Exquisite Orcish is apparently very weak..). That Silver Hand boss for the first Circle mission was a joke. He could instagib me with finishing moves when I had 2/3 hp left!
