Ok, first off this quest was fairly easy when i completed it as a lvl 18 Predator. Using Hunt is what is going to get you by the first two guards, but App 1 Hunt wont work so find App 2. I believe I purchased it from the trainer in Nettleville Hovel for around 17s. Once you pass the first two gaurds use tracking to find the mob you need to kill. I was surprised how easy this was once i knew that Hunt needed to be at app2 or higher, but dont make the same mistake i did and wonder upstairs. For some reason I forgot i had tracking (still a noob). But that pretty much sums it up, good luck!
