Eusis said:You only use Fire Keeper Souls from your inventory when your Estus Flask is +7, at that point it can't be reinforced so they're spare humanity items instead.
You can also drop them for friends when you coop. Because through your first playthrough the max you can get is +6 even if you kill all the firekeeper's because then you don't have a firekeeper to upgrade your flask. So if you give a friend one and he kills all but one of the firekeeper's he can get to +7 on his first playthrough.
