hi which files u have?
usually inside shops .cfg file you must see 255 and its for antitode, and all other potions too, or IMP / angel etc u just change that number of the item u wanna change the count and refresh shops simply.
now if you use other files then its another story
Hi, in this case you have to edit "ItemStack.txt" which is inside the "Data\Item" folder. First you write there the index (category * 512 + item index; for example if you want to add Healing Potion: 14 * 512 + 2 = 7170). Second at "MaxStack" you write 3, and lastly a "*" for "CreateIndex".
Now you can edit the shop files. At the "Dur" or "Durability" column write 3.
If you want to change something later in the quantities or stacking, just remember that you have to edit multiple files...
