Bone Thunder Staff is baws and you can solo it at like 9 or 10 untwinked.

Mini Ghoulbane. Hardest part of the quest is running from Surefall Glade, to Ak'Anon and back for the Regurgitonic, but a bored druid can help speed that up.
Drosco WILL spawn if you keep clearing the cube placeholders. Mammoth WILL spawn in the Surefall glade cave, just be patient with both. Neither should take an hour.
