<Sir/Ma'am>, we need tons of moolah to pay the Trade Prince and get off Kezan! Well, tons of it is just waiting for the taking down there in the Kaja'mine!
These are the last known deposits of kaja'mite anywhere. This is the raw stuff that made us the genius tinkerers and alchemists that we are today. If that's not worth a bazillion macaroons, I don't know what is!
Take some of my kablooey bombs and blowup the deposits. Then, pick up the chunks.
The bomb is a ground-targeted AoE. Use it on the big Kaja'mite deposits to blow them up in to three Kaja'mite Chunks. It's possible to use the bombs to stun the rebellious trolls, if for a second or so.
