what level you need to start each dragonborn quest, not just mq ? I tried wiki but didn't find them

u don't have to be a "level" to go to solsthiem you just head to the Windhelm docks and talk to Gjarlund Salt Sage. to start the MQ of dragonborn u need to at least have completed The horn jurgen windcaller from the greybeards. i wouldn't recommend going to solsthiem until you at least level 25 and up otherwise you will get your azz kicked (you already will anyway)

I'd recommend 30+. Beth thankfully made it a challenge.

Agreed. I am level 81, play on Novice difficulty and still get my rear end handed to me.

Level 1.

Considering you have to do a certain quest to even start the MQ, I doubt you'll be level 1 by the time you're done

I don't have to level up
