Creepers, TNT and other explosions can wreck ordinary chests and scatter your loot. Obsidian chests are built to stop that. They provide strong blast protection and still hold 108 slots per block, the same as the other top-tier chests.
Setting Up Blast-Proof Storage
1. Decide what needs protecting. Good candidates are diamonds, enchanted gear, rare drops, and anything you can't easily replace.
2. Get an obsidian chest. You can craft one, or upgrade an existing chest using the upgrade item for the obsidian tier. To upgrade, hold the upgrade item in your main hand, then Shift + Right-Click the placed chest. Your items stay inside during the upgrade.
3. Place it where explosions are likely. Good spots include:
- Near the outer walls of your base
- Next to TNT-based farms or quarries
- At a mining outpost where creepers wander in
Smart Placement Tips
- Group valuables together in obsidian chests. Keep cheap bulk items in lower tiers to save materials.
- Remember the blocks around the chest. The chest resists blasts, but nearby walls, item frames and other storage may not. Protect the whole room if you can.
- Need to see what's stored? Crystal chests show their contents through transparent sides, but they do not offer the obsidian chest's blast protection. Use obsidian for safety and crystal for display.
