Obsidian Chest

The Obsidian Chest is an upgraded form of the Diamond Chest, and along with it and the Crystal Chest, is the fifth tier of chests added by Iron Chests. It has 108 slots, which is eighty-one more than the standard Chest. Although it has an identical storage capacity to the Diamond Chest, it has an incredibly high blast resistance, making it impervious to explosions, even those from Nukes and Nuclear Reactors.
