 * Up to 6 can be put on the same block space, merging into one block.


 * 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.


 * 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. Will also break when pushed directly or with a block by a piston.
 * Stalagmites break if not attached to something below

 * Powder Snow
 * A variant of snow, Entities that walk over it will 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.

 * Wearing any piece of leather armor will stop 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, only available from the Creative inventory or commands such as, but natural generation is planned for future versions.
 * Senses vibrations such as block placement, footsteps, and projectiles, and emits a redstone signal.
 * Particle of the Vibration.gif Emits particles when it senses a vibration nearby.
 * A comparator connected to it will emit 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.

 * Used to store other items (except shulker boxes) inside of it.
 * Can only hold a stack of items, but is able to hold different types of items inside of it.
 * 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 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.

 * Contains blocks of amethyst and budding amethyst blocks, which are encased in a shell of calcite and tuff.
 * Also generates with a small air pocket nearby which may open into the geode.
 * Generally generates at or below sea level (y = 63).
 * Most commonly generates at lower levels (y = 0 to y = 40)
 * Overrides standard caves and ravines, but is overridden by abandoned mineshafts.
 * Currently has a high generation rate, presumably for testing purposes which was also done with ruined portals before.


 * 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 only be generated using buffet worlds with "Dripstone Caves" selected as the source biome or using custom world. Natural generation is planned for future versions.

Gameplay

 * Generates in the deep dark biome
 * Has a different top texture than the Sculk Block and Sculk Chute.


 * Sculk Something.png


 * Generates in the deep dark caves.
 * While this block's use and function is currently unknown, it is speculated that this block is the source of the other sculk blocks due to the block always appearing in the middle of each sculk growth. This could possibly mean that the other sculk blocks grow out from the sculk chute, however this is just speculation.
 * Has the same texture as the skulk block, even though part of the skulk chute is made of bones.


 * Sculk Growth.png


 * Generates in the deep dark cave biome.

Mobs

 * Goat.png Goat


 * This feature is currently available in beta development versions of Bedrock Edition 1.16.210.

 * Warden.png




 * Spawns in the new deep dark biome.
 * It is the first blind mob.
 * When sensing movement, it moves toward the source of the movement.
 * 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, like a snowball or an arrow, lands near the Warden, it causes the mob to head to the location of where the projectile landed, due to the projectile itself creating movement and noise, therefore distracting the warden.
 * Does not detect players that are sneaking.
 * Can detect players that are invisible.
 * Can detect players using elytra.
 * When aggravated for long enough, the warden follows the player continuously, regardless of any other distractions.
 * Attacks any mob that makes vibrations, not just players.
 * Can detect ringing bells.
 * Can detect players eating.
 * Incredibly strong, doing damage, bringing players wearing full netherite armor from full health to  health points.
 * Has at least health points, although it is estimated to have up to, putting it on par with the iron golem and ravager.
 * 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 use the energy of vibrations to move faster.
 * 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 3.2 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

 * Archaeological excavation


 * A new semi-underground structure where archeological items and ceramic shards can be found.


 * biome


 * New biome at the "deepest depths of the world".
 * Wardens can spawn here.
 * May contain candles.
 * Contains sculk blocks, and the new Sculk Sensor Blocks, a new block that responds to vibrations.
 * Contains a new Unnamed Block.


 * Dripstone caves
 * Will generate naturally in default worlds.




 * Generate below azalea trees.
 * Contains tall grass, glow berries, dripleaf plants, spore blossoms, moss blocks, moss blankets, clay blocks, azalea roots, and azalea saplings.
 * Can spawn axolotls.




 * Seems to be possibly a large tunnel-like cave.
 * Not much is known about this cave yet, but it was confirmed on Twitter by Henrik Kniberg.
 * It's a variation of caves rather than a biome, as stated by Henrik Kniberg.


 * Possibly contain "catacomb" style branching cave sections.




 * 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.

Gameplay



 * 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.




 * 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.




 * An action can cause vibrations in the air, which can be picked up by sculk sensors and wardens
 * Can be caused by walking (but bats?), block placing, block breaking, doors or trapdoors opening, chests of any kind opening, pistons activating, and projectiles such as snowballs, eggs, or arrows landing. This does not include ambient weather such as rain or snow.

World generation

 * Caves


 * Complete generation overhaul.
 * Many variations on cave types and cave design.
 * Biomes within caves introduced.




 * A new underground water level generation aspect has been introduced, which allows for certain areas of a world to generate with a specified water level different from that of another area (such as sea level).
 * Caves & Cliffs Mountains largersize.png.]]Allows for the generation of larger underground lakes and connections to oceans.
 * Allows for the generation of many underground waterfalls.
 * Allows for underwater entrances.




 * Height dependent generation.
 * Revamped, featuring some new small spruce trees on the slopes and ice or packed ice above the peaks.
 * Contain snow blocks, goats, and a new form of snow called powder snow, which is said to be "snowier than snow".


 * Ore veins


 * To be revamped, possibly to balance the generation of copper.
 * Some stone appears a little different and when that stone is mined, more of the ore should be found behind it.


 * Other Stones


 * Granite, Diorite, and Andesite spawn in layers of rock in straight lines instead of splotches.  Example-of-other-stone-generation.png

Blocks

 * Wool


 * Used to block a sculk sensor's ability to sense vibrations.

World generation

 * 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.

General

 * Height limit
 * May be increased. It is considered to change only in the overworld as stated by Jeb.
 * As of 20w49a. World-height related values are now exposed for customized worlds, which might confirm that height limit might get removed or increased.

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.
