Any difficulty, I guess. The real question is when should you start? E.g. after what quests?
well "main quest" side
Spoiler im just at the part for retrieving the horn of jurgan windcaller?
joined the imperial legion and
Spoiler my next mission is to invade windhelm
haven't even discovered markarth yet, i've focused myself with quests mainly around solitude due to my charicter being an imperial loyalist.
i just dont know the right time to take the leap into this dlc...
