Java Edition 22w13a

22w13a is the third snapshot for Java Edition 1.19, released on March 31, 2022, which adds the allay, ancient cities, reinforced deepslate, and fixes bugs.

Blocks

 * Reinforced Deepslate
 * A new block only found in ancient cities shaped as a large frame.
 * Is not craftable.
 * Is completely blast-resistant, and takes an incredibly long amount of time to mine (82.5 seconds).
 * Can be broken, but won't drop anything, even with silk touch.
 * Cannot be moved with pistons.

Items

 * Spawn Egg
 * Added allay spawn egg.

Mobs

 * Allay
 * Can collect the same items from the world as it holds in its hand.
 * If holds an item it got from a player, it will follow that player.
 * It can be made to hold an item by interacting with the allay (pressing ).
 * The item can also be removed by interacting with the allay (pressing ) while with an empty hand.
 * Able to drop items at nearby note blocks, and stay close to a note block that has been played near them.
 * When playing a note block near them, that note block becomes their favorite one for 30 seconds, and they will attempt to drop off items at the note block rather than at the player.
 * If they have items in their inventory, they will attempt to give them to their owner.
 * Sometimes spawn in cages next to pillager outposts (similar to iron golem), and inside woodland mansions.
 * Has a delay for picking new items after delivering items.
 * Immune to damage from its owner while holding an item.
 * Have health points.

World generation

 * Ancient City
 * Generates within the deep dark biome and includes all of the deep dark features within it.
 * Always generated at Y=-52.
 * Made of deepslate and its variants, basalt and its variants, and gray wool.
 * Contains soul sand, soul fire and soul lanterns, as well as candles and skeleton skulls.
 * Contains chests with unique loot, like the swift sneak enchantment.
 * Other valuable loot includes the "otherside" music disc, Potions of Regeneration II, enchanted books, enchanted iron and diamond leggings, enchanted diamond hoes, and enchanted golden apples.
 * If the frame of reinforced deepslate generates with a chest in front, it will always contain one golden carrot (a hint about how to open the secret door below).
 * Has different levels and open spaces, with several types of ruins and wall structures.
 * Some of these structures contain dark oak logs, planks, and fences; cyan, light blue, and blue wool and carpets; ladders; ice and its variants; note blocks; stone pressure plates; and iron trapdoors opened with levers.
 * Hidden underneath the frame of reinforced deepslate are several rooms containing redstone mechanisms that serve to introduce new players to their function.
 * There is a silenced sculk sensor that needs a signal strength of 8 to open a redstone door. Taking the golden carrot from the chest placed near the structure and eating it will reveal the entrance.
 * Each variant of the city center has a different redstone puzzle concealing the entrance, requiring slightly different strategies to solve.
 * The mechanisms are made with redstone dust, redstome torches, redstone repeaters, redstone comparators, redstone lamps, blocks of redstone, sticky pistons, a sculk sensor, a target, and a lectern.
 * One variant includes a lever, and another includes a furnace containing 24 deepslate and a wooden shovel.
