This mod introduces a variety of new resources and tools in your Minecraft gaming experience.
First of which, are the crystal ores that now appears in caves that you can mine and collect to craft the new items the comes with this mod, as well as new window panels that are shatter resistant.
You can then make crystal tools using the same recipe model as standard tools. They have a slightly higher durability than iron tools but less than diamond. What makes this mod even better is you can also make tools using bones as the handle. This will double the durability regular crystal tools have.
