My first Tabletop Campaign and I get the PCs from Hades...

Umm, they have 18,000g EACH at 6th level? Dude, huge mistake... Even if they found equipment worth that much, alyways remember that they can sell it only for half price... Ever heard of improved sunder feat? Rust ray? Rust monster? Destroy their weapons in the middle of a fight (not all, of course...), have a thief steal it from them, that'll teach them some humility, and it will solve your problems regarding killing everything you throw at them... My party is level 6, I think we have about 16 000g worth of equipment all together...
