Additions

Blocks

Copper Block

• Can be crafted with 4 copper ingots, and can also be crafted back into 4 copper ingots.
• Oxidizes and changes texture to a turquoise-green over time.
• Can be stopped from oxidizing by combining it with a honeycomb to create a Waxed Copper Block.
• Can be crafted into cut copper.

Copper Ore

• Generates randomly underground in small veins, but this has been confirmed to be a placeholder.
• Has the same rarity as iron.
• Generating starts at the same minimum level(s) as iron.
• Can be smelted into a copper ingot.
• Spawns in up to 5 blocks together.

Cut Copper

• Can be made into stair and slab variants.
• Oxidizes and changes texture over time.
• Can be stopped from oxidizing by combining it with a honeycomb to create Waxed Cut Copper.

Cut Copper Slab

• Oxidizes and changes texture over time.
• Can be stopped from oxidizing by combining it with a honeycomb to create a Waxed Cut Copper Slab.

Cut Copper Stairs

• Oxidizes and changes texture over time.
• Can be stopped from oxidizing by combining it with a honeycomb to create Waxed Cut Copper Stairs.

Glow Item Frame

• Placeable entities that appear to glow.
• Glowing entities do not affect the light level, appearing only as if lit up themselves.
• Items placed inside also glow.
• Crafted using an item frame and a glow ink sac.
• Includes application to maps.

Lightning Rod

• Can be crafted with 3 copper ingots.
• Lightning strikes within a 32-block radius get redirected to the lightning rod.
• Gives off a redstone signal with a strength of 15 if hit by lightning.
• Can be activated directly by throwing a trident with Channeling at it during a thunderstorm, though this does not produce a redstone signal.
• Gives a light level of 1.

Pointed Dripstone

• Can be either placed on a ceiling to create a stalactite, or on top of a block to create a stalagmite.
  • Can be combined to form longer stalactites and stalagmites.
• Thrown tridents break pointed dripstone, which also breaks when pushed directly or with a block by a piston.
• Stalagmites break if not attached to something below
• Stalagmites hurt entities that fall on top of them more than normal fall damage.
  • Damage is relative to height: For example, jumping on a stalagmite deals 2 of damage, and falling from 3 blocks deals 8 of damage.
• Stalactites can fall or break if unsupported, and break apart on impact, hurting entities they fall on.
  • Damage is relative to height: For example, one falling from 2 blocks deals 2 of damage, and one falling from 3 blocks deal 4 of damage.
  • They drip water or lava into cauldrons if a source block is placed above the stalactite, and gradually fill the cauldron. Water drips even without any water above the block (lava in the Nether), but does not fill the cauldron.

Powder Snow

• A variant of snow, Entities that walk over it sink into it.
• Leather boots can be worn to prevent entities from sinking into powder snow blocks.
  • Players can still crouch to descend with leather boots. Wearing leather boots also allows powder snow to be "climbed", like water or scaffolding.
• When inside a powder snow block, a frosty vignette appears around the player's screen and any entity inside starts freezing and taking damage after a short time.
  • Wearing any piece of leather armor stops the freeze effect.
• Can be collected and placed with a bucket.

Sculk Sensor

• A redstone component that sends and receives redstone signals wirelessly.
• Currently, it does not generate naturally, available only from the Creative inventory or commands such as /give, but natural generation is planned for future versions.
• Senses vibrations such as block placement, footsteps, and projectiles, and emits a redstone signal.
• File:Particle of the Vibration.gif Emits particles when it senses a vibration nearby.
• A comparator connected to it emits different signal strengths based on what caused the signal.
• Does not detect ambient weather such as rain.
• Wool blocks between the sensor and the cause of the sound prevent the sensor from detecting the sound.

File:Unidentified Sculk Block.png Sculk Trap

This image shows the sculk blocks in redstone, implying that the other sculk blocks also have redstone uses.

• Generates in the deep dark biome.
• Has a different top texture than the Sculk Block and Sculk Chute.
• May be used in redstone.

File:Sculk Something.png Sculk Chute

• Generates in the deep dark caves.
• Made of sculk and a bone-like material.
• May be used in redstone.
• Glows but does not emit light, similar to the glow squid or the glow item frame.

Sculk Veins

• Generates in the deep dark cave biome.
• Generates in a layer on top of blocks, similar to snow.
• Can be placed in all directions, like glow lichen.
• Some have parts that are transparent, allowing the player to see the block it is on top of.

Processing rubble

• A technical block associated with archaeology.
• At least comes in dirt and gravel variants.
• Created upon using a brush on what appears to be normal dirt or gravel.
• Has 16 layers.

Items

Brush

• Used to sweep debris away from archaeological items.
• Sweeps debris off archaeological items one layer at a time. If interrupted, the block it was being used on simply disappears, and does not yield custom block heights.
• Also comes in a blue-green variant:

Ceramic Shards

• Obtained with a brush at archeological sites.
• Come in different colors and different designs, each depicting a different picture, such as an ender dragon, a cow, Alex, a skeleton, a tree and a vindicator.
• Can be placed/customized on clay pots.
• Currently using placeholder art, according to Jasper Boerstra.

Bundle

• Crafted with 2 string and 6 rabbit hide.
• Used to store other items (except shulker boxes) inside of it.
• Can hold only one stack of items, but can hold different types of items inside the stack.
  • Items with smaller stacks, such as ender pearls, take up more room in a bundle, and non-stackable items take up the whole bundle.
• The bundle's contents can be opened by pressing use while holding it, throwing out its entire content into the world. When destroyed as an entity, it drops the items it currently has as well.
  • Right-clicking a bundle in the inventory empties one item from the bundle.
• Even though bundles are not stackable, bundles can be nested.
  • Can hold up to 16 bundles.
  • Only empty bundles can be placed in other bundles without using commands.
• Has a GUI when hovering over it.

Spawn Eggs

• The Warden spawn egg is visually confirmed but not yet implemented.

Mobs

Axolotl

• The first amphibian added to Minecraft.
  • Will dry out and start taking damage after 5 minutes of being out of water.
• Can be caught using a water bucket, like fish.
• Can be bred using tropical fish or buckets of tropical fish.
• Come in five different colors (leucistic, yellow, brown, white, and purple/pink, and a rare blue Axolotl).
  • Blue axolotls are very rare, with a ¹⁄₁₂₀₀ chance of spawning.
• Plays dead when damaged, receiving Regeneration I.
  • This regeneration ability is likely based on how real axolotls can regrow lost limbs.
• Attacks drowned, guardians, squids, glow squids and fish, damage not yet official.
  • Are always hostile to fish and squid, and hostile to drowned and guardians only when "tempted" by a player holding tropical fish.

Warden

A picture of the Warden and Iron Golem standing side by side

• Spawns in the new deep dark biome.
• The first fully blind mob (bats, despite relying almost exclusively on echolocation, still have basic eyesight).
• When sensing movement, it moves toward the source of the movement.
  • It follows and attacks players, mobs, and other entities that make vibrations.
    • It does not attack other Wardens.
  • When attacked, it path finds toward the player.
  • Seems to follow the same rules as the sculk sensor when detecting noise.
    • When it detects a vibration, the growths on its head rattle and light up, similar to the sculk sensor.
  • If any projectile (e.g. egg, snowball, arrow) lands near the Warden, the mob inspects the location where the projectile landed, due to the projectile creating movement and noise. This feature can be used in order to cause a distraction.
  • Does not detect players that are sneaking.
  • Can detect players that are invisible.
  • When aggravated for long enough, the warden follows the player continuously, regardless of any other distractions.
• Incredibly strong, doing 30 × 15 damage, bringing players wearing full netherite armor from full health to 7 health points.
• A mob designed to be extremely difficult and fled from.
• Has a way to counter the strategy of building up 3 blocks to avoid attacks.
• At least as fast as the player's walking speed.
• Seems to have knockback resistance.
• The warden's chest has a glowing core that appears to brighten and dim in tandem with the ambient lighting of the deep dark cave biome.
  • The core creates a low throbbing sound as it pulses. The sound and animation seem to speed up rapidly when the warden notices a player.
• Is about 3.5 blocks tall, making it one of the tallest mobs in the game, exceeding the iron golem and enderman in height and width (the same).

World generation

Dripstone Caves

• A new underground biome, consisting of a massive cave biome containing vast quantities of stalactites and stalagmites.
• Made up of primarily dripstone blocks and stone, with large clusters of dripstone blocks hanging from the ceiling, pointed dripstone on the floor and ceiling and many pools of water.
• Does not yet generate naturally in normal worlds, and can be generated only using buffet worlds with "Dripstone Caves" selected as the source biome or using custom world. Natural generation is planned for future versions.

Deep dark biome

• New biome at the "deepest depths of the world".
• Wardens can spawn here.
• Contains sculk blocks and sculk sensors.
• Contains grimstone.
  • Likely generates within the grimstone layer between -1 Y and -64 Y.
• May contain candles.

Lush caves

• Generate below azalea trees.
• Can be reached by following azalea roots underground.
• Contains tall grass, glow berries, dripleaf plants, spore blossoms, moss blocks, moss carpets, clay blocks, hanging roots, rooted dirt, and azalea variants.
• Can spawn axolotls.

Mesh caves

• Seems to be possibly a large tunnel-like cave generation.
• Not much is known about this cave variation yet, but it was confirmed on Twitter by Henrik Kniberg.
• Possibly contain "catacomb" style branching cave sections.

General

• More extreme and smooth terrain.
• Likely change to the generation of alternate stone types, to make them appear in larger but less numerous deposits.
  • Possibly seen in a screenshot tweeted by Henrik Kniberg, in which diorite appears to generate in a long and flat horizontal strip, rather than a small unevenly shaped patch.
• Ore generation will see further rebalancing and will influence the surrounding stone

Gameplay

Archaeology

• The player can find items and blocks in gravel and dirt inside the dig site structure by using the brush.
• Possible items shown in the preview footage include:
  • Ceramic shards of varying color that depict different images.
  • Diamond blocks and emerald blocks are probably not a part of this list and serve as a placeholder for something else.

Dimming of light

• While in the deep dark cave biome, the ambient lighting occasionally dims temporarily, limiting the player's visibility. This serves as a warning that the warden is nearby.

Planned changes

World generation

Mountains

The preview of updated mountain generation given during Minecraft Live 2020.

• Height dependent generation.
• Revamped, featuring some new small spruce trees on the slopes and ice or packed ice above the peaks.
• Contain goats, snow blocks, and powder snow.

Mineral veins

• Some stone appears a little different and when that stone is mined, more of the ore should be found behind it.

Other Stones

• Diorite or calcite and what appears to be tuff spawn in layers of stone in straight lines instead of splotches.

An example of how the other stones may generate

Unconfirmed features

Structures

Underground Cabin

• Seen in the Deep Dark biome during the Minecraft Live 2020 stream.
• Consists of a chamber with a cobblestone floor and stripped log support beams, containing 3 barrels, a blast furnace, and a large chest, with cobwebs and candles in and around it.
• May possibly not be a generated structure, but instead a construction built for the purpose of the Warden showcase.

Trivia

• This is the first Bedrock Edition update to add a new ore to the overworld since emerald ore was added.
  • Similarly, this is also the first Bedrock Edition update to add a real-world metal into the game since iron and gold ore was added.
