The following recipes are similar to vanilla Minecraft recipes, but use Biomes O' Plenty items:
Press F3 + F at the same time to see the durability of the items :D
Mud Tools: Same as normal tools, but with mud balls in place of ore. Sticks are still used, 32 uses.
Mud Armor: Same as normal armor, but with mud balls in place of ore, 32 uses.
Amethyst Tools: Same as normal tools, using amethyst for the ore, and iron ingots in place of sticks,2013 uses, nearly double of diamond tool uses.
Amethyst Armor: Same as normal armor, using amethyst for the ore, 640 uses, a little better than diamond armor.
Wood: The custom logs and planks in this mod can be crafted into anything that vanilla logs/planks can, from doors, to stairs, to jukeboxes. They can also be used as fuel.
