tbh, how can titanic saw take 5 months? do you spent 1 min per day with fishing? If i try hard to catch one I usually get 1-2 per day with average luck (including many silver sharks).

as duude said, try to catch the mooch before the window starts, it helps a lot. you should also use the 14angler weatherreport, you can semi afk the whole day and will never miss a single window

I think i spent 10 or more windows until I got just one bite, but well. Do you expect some newcomer to 1 shot t13? its endgame content, so it consumes a lot of time, the big fishing reward sounds even better than the t13 title
