So my idea I think would function mechanically similar to the Frozen fishing but would be something that would be year round. People could sacrifice chum in each fishing spot and then the following day whichever fishing spot received the most chum (with a minimum
amount required potentially) would then become "chummed" Which would function like a day long buff of the fish biting for that spot or increase the chance to get rare drops. I think this would be a good way for a lot of players to utilize the chum besides just selling it and away for the community to cooperatively work together.
