Title - didn’t get memory for Sacrolash on my first run, so I’m wondering if that means I’m SOL until I can get Soul Ash from this wing again i.e. weeks from now when it comes back
No, you can keep going.
you know that you cant get the memory if you dont do the quest chain to recover the runecaver memory first right? then you just do the wing at level 3 at least and you get it.
