Minecraft 1.20: The Update That Changed the World Again

1.20 is a hypothetical Minecraft update I conceived. It would be a major update, spreading through all 3 dimensions.
== Additions ==
=== Blocks ===
==== Azalea Wood ====
* Replaces the current Oak wood used in Azalea trees.
* It is flammable.
* Has the same functions as all other wood types, including but not limited to: crafting recipes, mining speed, and sounds.
==== Marzac ====
* A new stone variant found in the End, spawning on Large End Islands.
* Can only be mined with a Netherite Pickaxe.
* Has a dark purple/blackish color.
==== Marzac Bricks ====
* Brick variant of Marzac.
* Found in Illusioner Temples.
* Can be crafted with 4 Marzac in a square, or cut with a Stonecutter.
* Has Variants like Mossy Marzac Bricks, Chiseled Marzac Bricks (its texture has the illusioner face on it), or Cracked Marzac Bricks.
==== Rotting Planks ====
* Cannot be crafted or obtained in survival; mining it (even with Silk Touch) drops nothing.
* Spawns in Woodland Mansions and Abandoned Villages (on the floor).
* Comes in all Plank types (including Azalea), even though they don't all spawn naturally.
* Gets more cracked as an entity stands on it.
* An axe is the preferred tool.
==== Soul Ice ====
* Doesn't spawn naturally.
* Is created from flowing water touching a Soul Lava source block.
* If a mob/player steps on it, they get freezing damage, which cannot be prevented with leather boots.
* Has soul particles only when a mob/player steps on it.
==== Soul Lava ====
* Spawns in the Soul Sand Valley in small patches.
* It is blue.
* Can be made by placing a Lava source block on Soul Sand or Soul Soil.
* It flows as fast as regular Lava in all 3 Dimensions.
* If a flowing Soul Lava block reaches a block other than Soul Sand or Soul Soil, it will stop flowing and won't go on top of the block.
* It scares away Piglins.
* It can be placed in a cauldron.
* It doesn't burn down wood.
* Has soul particles.
===== Water mechanics =====
* All the below don't work in the Nether, as water can't be placed there (except cauldrons).
* If flowing water touches a Soul Lava source block, it turns into Soul Ice rather than Obsidian.
* If flowing water touches flowing Soul Lava, it generates Blackstone rather than Cobblestone.
* If flowing lava touches a water source block, it turns into Blackstone rather than Stone.
=== Items ===
==== Bucket of Soul Lava ====
* What happens when a bucket picks up Soul Lava.
==== End Crawler Tooth ====
* Drops from End Crawlers.
* Can be used to brew Potion of Climbing.
==== Potion of Climbing ====
* Brewed from adding an End Crawler Tooth to an Awkward Potion.
* Allows a player to climb walls (without the use of ladders, like a Spider, Cave Spider, or End Crawler.
* Can be used to make Lingering or Splash Potions.
===Mobs===
==== End Crawler ====
* An End variant of the Spider.
* They spawn in Illusioner Temples due to spawners and in/around End Cities.
* If all of the End Crawlers in an End City are destroyed, then more will generate.
* Even if all of the blocks of the End City are destroyed, they will still spawn, as long as the endstone in the of the former End City is still there.
* Has a yellowish/blackish/purple body texture.
* Has dark blue teeth and crimson eyes.
* Can climb walls just like its' Overworld counterparts.
* The sounds it makes are like a mix of an Enderman and a Spider.
* If it is in the End, it is always hostile towards the player and any mobs that aren't native to the end; If it attacks, the thing it attacked gets five seconds of the Darkness Effect.
* If it is not in the End, it will camouflage with whatever blocks it is in front of, including air, and run away from a nearby player.
