Have you ever wanted to make obsidian more useful? Well now you can! Using my first mod ObsidianStuff you can craft your own tools made of Obsidian, yet that's the only thing you can do! Obsidian tools, but soon I'll add BunkerBlock, and Obsidian armor!
Also remember that ObsidianStuff as well as many others MCP-Based mods will not be updated anytime soon! Do Not Ask!
So if you want to keep playing please don't update to 1.0.0 or Use MCNOSTALGIA.
