- I am not offered the quest "The Legion Returns"
- I boosted to 120 and I don't have a hearthstone to teleport to Dalaran
- Abandoned "The Battle for the Broken Shore" and cannot pick it up again
I am leveling without a boost
If you are leveling your character through regular play visit the Command Board on your capital city Stormwind or Orgrimmar and pick up the quest The Legion Returns (Alliance) | The Legion Returns (Horde) and start the introductory quest line to the Broken Shore.
You must be at least level 98 to start this quest. If you aren't offered this first quest it means you have already completed it and you are ahead in the quest line. To find the next quest, open the map and look for the quest markers.
I boosted to 110
If you boosted to level 110 check your inventory and look for the Broken Isles Survival Kit. It contains a Dalaran hearthstone to teleport you to Dalaran.
I boosted to 120
When you turn this quest in, Recruiter Lee (Alliance) or Holgar Stormaxe (Horde) will give you a choice to skip the introductory quest line to the Broken Shore. If you choose to skip, you will be immediately teleported to Dalaran and you will be asked to hand in the last quest called In the Blink of an Eye —hand in this quest to receive your Dalaran hearthstone.
