The Auto Compressed Hammer will automatically hammer Compressed Blocks in its inventory as long as its provided with some energy.
It used to accept RF, but now it only supports Fuwafuwagy.
The Auto Compressed Hammer is crafted with a Compressed Diamond Hammer in the center, iron ingots left and right and Iron Pressure Plates at the top and bottom.
If a mod adding steel is loaded, it will require steel ingots instead of iron.
To speed up an Auto Compressed Hammer, one can insert additional Compressed Diamond Hammers into the two upgrade slots available. These hammers can also be enchanted with either Unbreaking, Fortune or Efficiency.
