“The concoction is finally ready, but before I can put my seal of approval on this strain, we'll need to run a field test.
Speak to Bat Handler Maggotbreath, here at High Command, and requisition a bat. The bat will take you to the Dawning Isles, east of here across Lordamere Lake, right into the heart of depravity itself - the Vile Fin murloc dens!
Use the concoction against the murlocs and report the results back to me.
Those results being that you killed them all, as commanded!”
