A Weapon of Doom

Gems? For me? For havin' such big ears, them elves don't listen so well. Let me say it slow, so you're sure to understand: I ain't helpin' you, 'specially not when I'm caged up without a drop of beer in sight! Hm ... there's a thought! I'll make a deal with ya. If you can bring me somethin' to wet my gullet, then I might just consider lendin' you a hand with this thing you want built. Might as well leave the stones here, though; wouldn't want nothin' to happen to 'em, would we?

Return to Kelysian's Landing and find a keg of Bugman's Extra Best XXXXXXXX. Get the beer, and bring it to the Captured Engineer so he will finally help you.
