Any idea if fishing the "Crockolisks in the City" effect helps here? I've been fishing the sewers off and on for over a year, caught him with what was then my main after a full week and close to 800 casts. Got the fishing bug with my new main, and fished on and off over several months, probably around 600 casts. Today, fishing the sewers with the quest, caught him in under 40 casts. One experience is entirely anecdotal, but I was wondering if anyone else had this happen also.
