Just wait until the metal bubble slimes and the metal slime kings start showing up. You also get to deal with gold golems on one of the islands in DQ8, but they aren't as much of a tease as the metal slimes and you can generally kill them consistently and reap a huge reward in gold.
Yeah, my wife and I both wanted to give Charmless a good kick in the you know where. I wonder if Yuji Hori was watching the Scooby Doo episodes with Scrappy when he was doing the writing for DQVIII. :)
