So, I'll to tell you everything I know about Master Fishing Rod.
First of all, to get one you must do something. Bring me 40 Nimble Fish.
It doesn't matter how you get them. The point is that you bring me the exact number I'm asking for. It's the main ingredient.
Bring me 40 Nimble Fish, and I will reward you with materials for your Master Fishing Rod.
