Hi forum!. Well the tittle should describe this thread.
Today I was curious about that man that can turn Holy Water into wine (aka Grape Juice) but turns out that the npc is very annoying making it; you get like 10 chat-windows before the Grape Juice and I think it should be faster, taking in count that you must collect/buy empty bottles and then make the holy water (-unless you buy everything-).
So, my suggestion is simple, simplify the quest and make it faster like Cursed Water Npc where you must select "make it" or "nevermind". *I forgot the options I'll check it later*.
