Mielon's The Sift

Update 2.0 changelog:

• Reworked The Sift’s world generation. The dimension now has 11 biomes, including Coral Meadow, Coral Forest, Organic Desert, Corrupted Sift, and three distinct underground biomes. You’ll also find new cave entrances, Ichor terraces and canyons, and huge rib fossils in the Organic Desert.
• Added three tides that change the sky throughout the day. You can sleep during Endure Tide or thunderstorms. Watch out for Stalkers and Scavengers during Endure Tide.
• Added Abandoned Camps, Ichor Domes, Soulshale Shelters, and Soulshale Towers to the Sift. Abandoned Portals now have biome-specific designs and loot.
• Added explorer maps that lead to Abandoned Camps and the buried Sculkers’ Lair. The lair is a new dungeon filled with Stalkers and Scavengers, with Royal Sculk and a Monarch Upgrade Smithing Template to discover.
• Added the Monarch, a boss you can summon by building a totem with Ichor, Soul Block, Soulshale Totem, Royal Sculk and a Sculkflower. The already built totem without the Sculkflower can be found in the Sculkers' Lair. Defeating it drops a Monarch Membrane, which you can use with the upgrade template to turn regular Elytra into Monarch Elytra. Press jump while gliding to gain altitude.
• Replaced the old Sifter mob with three different Sifters: Seedling, Nester, and Pollinator. They each fight differently, and Pollinators can spit explosive drool.
• Added Sifter Hide and the Sifter Cap. Wear the cap and Sifters will leave you alone unless you provoke them.
• Added Slabbers and Nuzzles. You can breed both with overgrown plants, and Nuzzles can be dyed and sheared like sheep.
• Added Blub variants and Blubby Berries. Blubs can eat ripe berries from bushes and climb on top of each other to form little towers. Blubby Berries are now also used to tame Blubs instead of the Soul Block.
• You can now build your own Echo Golem using Polished Soulshale and a Carved Pumpkin.
• Reworked Ichor. It now drains your health if you’re unprotected. Soul Absorption I on a chestplate prevents the damage, and Soul Absorption II turns exposure into Regeneration. The enchantment also changes the effects of Ichor Bottles and Ichor Snowballs.
• Added Soulshale with polished, brick, and chiseled variants, plus stairs, slabs, walls, and its own ores. Also added the full Ash Willow wood set and new coral and sculk vegetation.
• Added storage blocks for Charoite and Siftite. Siftite Blocks can be used as a Beacon pyramid material, and Siftite Ingot can be used to power it up.
• Updated the portal visuals and added feedback when you play the wrong note sequence. The melody plays back until the first wrong note, then glitches and turns the beams red.
• Added 10 ambient tracks by Lealeanz and new creature sounds from Minecraft Dungeons II
• Added the 3x3 Monarch painting.
• Added 16 advancements covering the new structures, Ichor, Sifter disguises, Blub towers, and the Monarch fight.
• Updated Polish localization and added Russian and Brazilian Portuguese. Thanks to Frumptle for Russian and Grelinho for Brazilian Portuguese. New lines that are still awaiting translation appear in English.
• Changed some loot tables, including bartering with Singer
• Added spawn_rifts gamerule
• Fixed a bunch of bugs with portal travel, mob behavior, and world generation.
• Probably a lot more stuff I forgot about lol
