Looked but couldn’t find. Do you need to finish Ultimate to go into any of the new places.
Malmouth, Gloomwald or Borrow.
Port Valbury part of Ultimate and need to get to Malmouth?

You need to talk with Inquisitor Creed in Fort Ikon after killing the Loghorrean, then you’ll be able to explore the expansion areas.

Do you need the expansion to travel further? It doesn’t show an aetheral crystal to break, it’s just a wagon burning. I finished normal.
