Obsidian Tools/Armor/Dimension Mod
This is a mod that adds tools, armor, a sword, and a new Nether-like dimension, all made of obsidian. In the Obsidian Dimension, you will find Snowflake Obsidian, which will replenish your hunger.(Snowflake Obsidian was long believed to have magical healing properties.) The crafting recipe for the tools and armor is the same as vanilla tools, but with obsidian instead.
