This suggestion I have seen somewhere but haven’t heard from it again and not sure is it been answer from BB?
I really like this idea so I bring it UP AGAIN
According to my research, saltpeter also know as Potassium nitrate is a chemical compound with the formula KNO3. It can be use as gunpowder but aslo can use as food additive which added to food to preserve flavor or enhance its taste and appearance
So my suggestion is making a buff that last longer with saltpeter
New buff: Family feast (any other name can be suggest here)
Resources need: 200 fish + 100 bread + 40 sausage + 20 saltpeter
For (x25) 5000 fish + 2500 bread + 1000 sausage + 500 saltpeter
This buff can be produced in the Provision house
Effect: This item buffs up production for 10 hours by x2.
From other guilde member Incontinentius and cookingfat suggest that saltpeter can be use as fertilizer and need better use for it so
special buff: wheat fertilizer
Resources need: 240fish + 120bread + 40 sausage + 40 saltpeter +40 exotic wood
For (x25) 10000fish + 5000bread + 2000sausage + 1000saltpeter +1000 exotic wood
This buff can be produced in the Provision house
