Levels 1-10
Finish Coldridge Valley before moving to Kharanos. Dun Morogh's roads leave room to reset, but the wendigo and Frostmane caves, snowy camps, and eastern named targets do not.
Keep the western caves optional
The Grizzled Den can end in the first controlled chambers. Frostmane Hold asks for a deeper scout, while Tundra MacGrann's Stolen Stash depends on a cave patrol window. Neither needs to close a solo starting-zone pass.
Finish the east with help
Protecting the Herd and A Pilot's Revenge are group stops, not proof that the zone is unfinished. Separate them with a repair and bag-space reset in Kharanos or Gol'Bolar.
Where next
Continue to Loch Modan after level 10. Use the eastern road only after training, repairs, and emptying your bags, then make Thelsamar the reset point for each separate trip.
