We currently have a merit for getting beat with the trout temporarily weapon this could be expanded upon of which I have a suggestion for and would work as follows:
The first merit would remain the same of getting beat with a fish.
The next merit would be be beat up or get beaten up with a fish 100 times this would also award a title called fish slapped.
And the final merit would be get beat up or beat up someone with a fish 1000 times and this final merit would award a merit a t shirt that says "I got beat up with a fish 1000 times" and a title called nice day for fishing.
I think this would add a touch of humour to the fish merits as well as making the trout a more used item.
