Specialist Cogwheel at Drak'Sotra has asked you to use the Tangled Skein Thrower in order to cause the destruction of 5 Plague Sprayers.
5x Plague Sprayers webbed and destroyed
There! One tangled skein thrower ready and waiting for you to take those plague sprayers down.
You just aim and let loose. The webbing should foul up their hover spells long enough to cause them to crash to the ground just like Kolramas.
Kind of poetic. I like that!
