Fluked into the raft as a lvl 48. I believe it is located in the swamp area. Follow the water ways within,,  you should be able to find it. It is partially submeged, 1/2 on shore, 1/2 in water. Upon inspecting the raft. Go to the center of creek, and dive under. U will find a backpack. Th
is is what starts the quest. Follow the directions and you'll be fine. At one point, you will drop the sword off in winterspring. The mod is located just as you come riding into winterspring. Not far in. Remember to pick the sword up before going back to tanaris.
The final mod is a lvl 55 elite. You need to equip the rod you were given, and activate it whenever it is charged for another shot. At lvl 49 now, i gainfully earned the help of a lvl 60 tauren hunter ,, in return 5 gold. He said sure came up, and folks, The boomerang is a novelty, but the sword is great. (compared to what i had, lvl 42 dagger) (linkens is at least lvl 53). Change talents around, work around sword. ya, i'm glad i did it.  Since i don't have a big guild and don't run instances. Anybody have an opinion for offhand?. I'm 51 now. Think i'll buy julies dagger for offhand,, opinions???
