I want to be able to reforge weapons to make them usable as fishing poles. Or the reverse. Let's say 40% weapon DPS changes to fishing, though still usable for combat. On the reverse, a fishing pole can be reforged, gaining DPS (though not the inverse of 40%, since that would end up overpowered) and will no longer be usable as a fishing pole. But it looks like a fishing pole and is perfectly suitable for beating people to death.
After all, who doesn't want to use non-fishing pole items as fishing poles? Even the goblins get to use dynamite.
