Smelt tools, armors, horse armors, clock, compass, shears, flint and steel, bucket and and get their materials.
Obtain ice from water, snow and a little strange recipe who use redstone and iron ingot.
Use 1 up to 8 potions bottle with 1 up to 8 cookies or 1 to 4 breads ( in a single slot ) to obtain 1 up to 8 donuts with potions effect. They are stackable and more easy to use add they do not fill your inventory.
Just this for the moment, but I will upgrade this mod with better stuff soon.
