Cracked Obsidian: Destructible Obsidian for Minecraft Raids
Obsidian has always been the ultimate flex for base builders. Stack a few layers of that purple-black rock around your vault, and you can basically ignore any raider who shows up with TNT. But that invincibility is exactly the problem. When a wall cannot be broken, sieges turn into boring stalemates, and the thrill of defending your base disappears. Cracked Obsidian changes all of that by turning the toughest block in the game into something that can actually be beaten, without making it feel like wet paper.
What Cracked Obsidian Actually Does
This add-on gives obsidian real durability against explosions. Instead of shrugging off every blast forever, obsidian now absorbs a limited number of hits before it finally gives way. The block progresses through damage stages, visually cracking as it takes punishment, so you and your attackers can see how close a wall is to collapsing. That visual feedback alone makes raids far more dramatic than the old "fire and forget" TNT spam.
Even better, you do not have to tear down and rebuild your defenses after every skirmish. The add-on introduces an Obsidian Glue item that lets you repair damaged obsidian blocks on the spot. Instead of mining out each broken block and placing a fresh one, you patch the wall in place. For anyone who has spent an hour replacing a blown-out bunker wall block by block, this quality-of-life feature is a genuine relief.
Damage Stages and Explosion Resistance
Two core values drive how the add-on behaves, and both are configurable:
- Damage Stages — the total number of explosions a single obsidian block can survive before it breaks completely.
- Explosion Resistance — controls the blast radius at which explosions start damaging obsidian, and sets the strength threshold an explosion needs to hurt it at all.
That means server owners can tune the difficulty to taste. Want obsidian to be nearly unbreakable but still technically destructible? Crank the stages up. Running a hardcore PvP server where no wall should last forever? Lower the numbers and watch sieges become genuinely tense. Because these values live in a config file, you can fine-tune the balance without touching any code.
Supported Minecraft Versions and Loaders
Cracked Obsidian is built for modern Minecraft Java Edition and is distributed as a mod rather than a datapack, which means it needs a compatible mod loader to run. It is designed to work with the Fabric and Forge ecosystems on current 1.20.x and 1.21.x releases, so check the version list on the project page before you commit to a download. If you play on a server, everyone connecting will need the mod installed for the damaged block states to render and behave correctly. Mixing it into a vanilla client will cause mismatches, so keep your modpack consistent.
If you would rather skip the manual folder shuffling, the foxygame.net launcher handles Cracked Obsidian as a one-click install and automatically keeps it updated whenever a new build drops for your exact game version, which saves a lot of trial and error. It is a convenient route for players who juggle several modpacks at once.
How to Install Cracked Obsidian
Getting the add-on running is straightforward once your loader is set up. Follow these steps:
- Install a compatible version of Fabric or Forge for your Minecraft release.
- Place the mod loader's API files into your mods folder if the loader requires them.
- Download Cracked Obsidian from the official project page and confirm the file matches your game version.
- Drop the .jar file into the mods folder inside your Minecraft directory.
- Launch the game, open a test world, and blast a piece of obsidian to confirm the damage stages are working.
- Adjust the config file if you want more or fewer explosions before a block breaks.
Once installed, craft or obtain Obsidian Glue and keep a stack in your hotbar during raids. Repairing mid-fight can be the difference between holding your vault and losing everything inside it.
Why It Belongs in Your Modpack
Cracked Obsidian solves a design problem that has quietly annoyed builders and raiders for years. It keeps obsidian valuable and tanky while removing its absurd invulnerability, adds a repair mechanic that respects your time, and hands the balance decisions to the player through config options. Whether you run a faction server, a survival SMP, or a private world with friends, this add-on makes base defense an active, strategic part of the game instead of a solved equation. The mod is free to include in any modpack you publish, though redistributing it as your own work is not allowed. Grab it, tune the numbers, and give your obsidian walls a fighting chance to actually fall.
