Allow us the chance to get trinkets and moonstone shards when using Koda. With the achievements of getting those locked only by manual fishing it makes it more difficult for people who have issues dealing with the fishing mini game.
I am not a fan of adding trinkets to Koda when fishing, because using Koda is my main method of obtaining food, and I wouldn't like it if I have to pay increasingly more to get the same amount of food because of trinkets being added.. I do however definitely see the need/desire.. I see two options that would not decrease the amount of fish collected from Koda. Either add the option to let Koda fish specifically for trinkets OR add trinkets (and shards) as 'bonus' drops, that do not take away from the amount of fish you can obtain from a trip.
