Pulling a Fast One

Oh, I know who those rebel bandits are, and I know where they've taken the chest. There are far too many of them for one person to take on, it's no wonder none of the idiots the Purser sent came back. No way to deal with that many, other than base cunning. I can't pull this off myself, but you've got a good set o' legs so you should manage all right. With the saltpeter you brought I've been able to finish the smoke bomb I've been workin' on. It's dead simple: find the chest, then get ready to use the smoke bomb. When they notice you, throw it down to make a hasty getaway. Easy.

Find the Heavy Chest at the Rebel Bandit camp northwest of the Fields of Ruin.
