Bedrock is the strongest block, but you cannot break it in survival mode

Bedrock is the hardest block in Minecraft. It has infinite hardness, meaning no tool, weapon, or explosion can destroy it. Bedrock forms the bottom layer of the world and the top of the Nether dimension, creating a barrier you cannot pass through during normal gameplay.

If you are playing in survival mode, bedrock is unbreakable by design. The game will not let you mine it, blow it up, or remove it any other way. In creative mode, you can place and break bedrock freely, but that is a different ruleset where you have unlimited resources anyway.

For practical purposes in survival mode, the strongest block you can actually break and use is obsidian. Obsidian takes the longest to mine of any breakable block and resists most explosions, making it the real answer if you are building something that needs to last.

Key Takeaways

  • Bedrock cannot be broken in survival mode and forms the world boundary at the bottom and top of dimensions.
  • Obsidian is the strongest block you can actually mine and use, requiring a diamond or netherite pickaxe and taking 50 seconds to break by hand.
  • Obsidian resists most explosions, including creeper blasts and TNT, making it ideal for protecting structures.
  • Crying obsidian, found in the Nether, looks similar to obsidian but breaks much faster and cannot be used for blast protection.

Why bedrock cannot be broken

Bedrock exists to set the boundary of the Minecraft world. Without it, you could dig infinitely downward or upward and fall out of the map entirely. The game treats bedrock as a permanent wall that defines where the playable area ends.

The only exception is in creative mode, where the normal survival rules do not apply. Creative mode gives you access to every block and the ability to edit the world freely. If you want to break bedrock, switching to creative mode is the only way.

Some servers and custom maps use commands to remove bedrock or make it breakable, but that requires administrative access and is not part of standard Minecraft. In the vanilla game as most people play it, bedrock is simply not an option.

Obsidian: the strongest breakable block

Obsidian is formed when water flows over lava source blocks. It appears as a dark purple-black block and is one of the most useful defensive materials in the game. To mine obsidian, you need a diamond pickaxe or better (netherite pickaxe). A stone pickaxe or lower will not work.

Mining obsidian by hand takes 50 seconds. With a diamond pickaxe, it takes 3.75 seconds. With a netherite pickaxe, it takes 2.85 seconds. This is significantly longer than other blocks, which is why obsidian is so valuable for protection.

Obsidian resists most explosions. A creeper explosion will not destroy obsidian blocks, and TNT will not either. This makes obsidian the go-to material for building bunkers, protecting valuable items, or creating structures that need to survive combat. The only explosions that can damage obsidian are the Wither boss and the Ender Dragon, both of which are end-game threats.

Other extremely hard blocks and their uses

Crying obsidian is found in the Nether and looks similar to regular obsidian, but it is much weaker. It breaks in about 20 seconds with a diamond pickaxe and offers no explosion resistance. Do not confuse it with regular obsidian when building defenses.

Reinforced deepslate is a block added in newer versions that is very hard to break, but it is primarily decorative and does not offer the same protection as obsidian. It takes longer to mine than obsidian but serves no practical survival advantage.

Ancient debris is the ore that drops netherite, the strongest tool material in the game. Ancient debris itself is very hard to mine and requires a diamond pickaxe, but the blocks you craft from netherite (like netherite blocks) are mainly for storage and decoration, not structural protection.

How to find and create obsidian

The easiest way to get obsidian is to find lava and water. Pour water over a lava source block, and it will turn into obsidian instantly. You can create obsidian farms this way by setting up a repeating pattern of lava and water channels.

Obsidian also spawns naturally in the Nether, in ruined portals, and around lava lakes in the Overworld. If you explore caves near lava, you will often find obsidian already formed where water and lava have met.

The Nether is the fastest source of large amounts of obsidian. Bring a diamond pickaxe, find lava lakes, and mine the obsidian around the edges. A single trip can yield dozens of blocks if you know where to look.

When obsidian is not enough

Against the Wither boss, obsidian will not protect you. The Wither can destroy obsidian blocks with its explosions, so you need to fight it in the open or use other strategies like hiding behind bedrock (in the End dimension where bedrock is accessible) or using shield blocks.

The Ender Dragon also ignores obsidian protection. If you are building a base to protect against the dragon, obsidian walls will not help. You need to either fight the dragon or build your base far away from where it flies.

For everyday protection against mobs, creepers, and other players on multiplayer servers, obsidian is the strongest choice. It is the practical answer to "what block should I use to protect my stuff" in almost every situation.

Frequently Asked Questions

Can I break bedrock with commands or mods?

Yes, but only if you have access to commands or install mods. In vanilla survival mode without commands, bedrock cannot be broken. Some servers allow bedrock breaking with special permissions, but that is a server rule, not a game feature.

Is netherite stronger than obsidian?

Netherite is a stronger material for tools and weapons, but netherite blocks are not stronger than obsidian blocks. Obsidian is still the best choice for building protective structures. Netherite tools just mine obsidian faster.

What happens if I try to break obsidian without a diamond pickaxe?

The obsidian will not break. Your pickaxe will not damage it at all. You will waste time and durability on your tool. You must use a diamond pickaxe or better to mine obsidian successfully.

Can I use obsidian to protect against all explosions?

Obsidian protects against creepers, TNT, and most explosions, but not against the Wither or Ender Dragon. Those two bosses can destroy obsidian. For everyday use, obsidian is your best defense.

Where is the easiest place to find obsidian?

The Nether has the most obsidian. You can also create it instantly by pouring water over lava source blocks in the Overworld. If you have water and lava, you can make as much obsidian as you need.
