Use Ban's Explosives to destroy 6 Osul Ballistas.
The yaungol's siege weapons - those ballista spearthrowers down there - are tearing apart our defenses both at Longying Oupost and in Kun-Lai Summit.
Those terrible weapons must be destroyed.
Take these explosives. I've covered them in the pitch that you collected.
Toss them at those ballistas, and we'll give the yaungol a little taste of their own medicine.
