 * 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.
 * May be used in redstone as seen in this video when they talk about the sculk sensor.


 * 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



 * Used to sweep debris away from archaeological items.

 * Warden Spawn Egg.png The Warden spawn egg is visually confirmed but not yet implemented.

Mobs





 * 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 damage, bringing players wearing full netherite armor from full health to  health points.

 * 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

 * biome

 * 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.




 * 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 has further rebalancing and influences the surrounding stone.

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 for something else.
