i've gotten two giant webfishes from town pools. i fish a lot though, plus i've been playing tl2 almost exclusively since i got it, so i have a level 51 engineer and a level 19 embermage. and in the time it took to get that, i've found two giant fish, both of them webfish, and both from town fishing holes. --- "bomb the living bejeezus outta those horses. that's not enough."

It's funny, On one character I have NEVER seen a giant fish. And on another, I got one on my third cast in the first town. And 3 since. --- "This is just here to make my posts look bigger than they really are" - My Signature
