Refined Obsidian is a handy block crafted with 9 Obsidian Ingots. It serves as a normal decoration block, but with a small glow. When shift+right-clicked, it will display a GUI that credits the mod's developer, aidancbrady, as well as an information panel displaying the mod's current version, most newest version, and latest news. You can update the mod's core module directly by clicking the 'Update' button. It will delete your current Mekanism core module and replace it with the latest version. Note that this process is multithreaded, allowing you to continue playing while it downloads.
