Zafirah has given you an illusion potion so you can mingle in the caves to the northeast ( 1446, -125, 3064 ) /waypoint 1446, -125, 3064 where the vermin seem to be concentrating. She has asked that you seek out any signs that the vermin are intelligent. Note that you cannot have your mount on when using the illusion form. Mining or gathering collectibles while in illusion form causes the illusion to break.
Note: you must be minimum of level 77 in order to use the charm and change illusion form. You can get a replacement illusion from Zafirah by hailing her. Mining cancels the illusion and you have to get another one.
Use the illusion potion and look for signs that the vermin are intelligent.(You have to cancel your mount for it to work)
