I agree with Rotgut. All the books have different recipies. There has got
to be more than just the fishing pole. Sounds like a joke at our expense.
If the combo to the fishing pole is in there, maybe the gnomish fireworks or
other combos are in there...the fishing pole would not sell for as much as
fireworks would, so you'd figure that these "elite tinkerers" would be
flooding the market with fireworks or any other contraption...doesn't look
like it's happend....maybe the found a rare drop on a rare mob that drops
the pole and that's how they're getting their supply...

Just a thought
