potion pack allows us to stack eight beneficial potions into “stacks”, chaining eight potions together on the crafting table. Thus we will have eight potions in a single box, whereas without the mod we would have eight boxes occupied by potions.

If we join eight potions with thread on the crafting table, we will create a pack of potions which, when used, will all be in the same place, so we will not have to use the mouse wheel to select one individual potion to use, but rather a place where we can use all eight potions.
