Dragon priests. You never know when you're going to run into one. The fights are fairly challenging. The masks are [censored] awesome. And you get a sweet extra mask when you collect all of them. Love hunting for priests.

Immersion.

dragon priests

and those draugr with shouts - they're pretty challenging

Thalmor. All of them.

And it's fun to wipe out a camp of Stormcloaks or Imperials (both are fair game), the resurrect them with the Ritual Stone power.

Deer

lol...

They are fun to chase, and punch.

Anything goes but how I do it is a different story.

Time to time I just swap. Typically stealth with melee or range, conjuration and range or melee with restoration.

stormcloaks and bandits..... basically the same, but bandits are a little bit smarter.


edit: also killing every thalmor i meet outside of cities.
