Extrathings:
Is a mod of fun and usefull things like a new ore which can be made into new items.
Like for example new tools like a pickaxe, axe, sword, shovel,hoe and hammer which will make mining a lot easier for ores.
We also have tools which make it easier to find ores like the ore detector and tools for the builder like the inventory cobblestone generator.
You can also use the new extra chamber to get items like the ore detector or turn coal to diamonds.
Also the fuse chamber allows you to combine items into new items.
