The Coffee Maker is a block used to make Coffee, a potion-like item that gives the user several buffs.
To use the coffee maker, you need a Empty Cup, <coffee> Coffee Beans, which can be found in the wild, harvested and planted on farmland again, <rf> CF/t and <water>mB of Water per cup brewed.
On the coffee maker recipe pages at the back, to see what the item does, just hover over the Cup of Coffee.
To actually give your coffee some buffs, put some of the items shown on the later pages into the slots on the right.
The more slots are filled up with one item, the higher the Amplifier of the effect will be. The Maximum Amplifier is the max amount of items to be put into one coffee.
Order matters: When using, for example, Milk (to see what it does exactly, go to a later page), you are going to have to plan the items out inside the numbered slots in such a way that it brews the coffee you want.
This is an example of a recipe making a coffee containing Fire Resistance 1 for 0:20 and Speed 1 for 2:30.
Milk is an important item when brewing coffee: It adds 2 minutes to all effects of items in slots with lower numbers while removing 1 amplifier. When the amplifier of an effect is 1, however, it will remove the effect.
The fact that you're reading this means that you either have HarvestCraft installed, or that you're looking at the lang file.
This does the same thing as Milk, but for veggie guys.
