Potions

• Ice Crystal items can be used to brew Freezing potions, which gives you Slowness and Mining Fatigue.

Structures

• Lost Explorer Camps generate under frozen biomes (in ice caves) between Y=-30 and 20.
  • Lost Explorers trade you materials from the surface for things found underground
  • Because of a Minecraft bug, Lost Explorers do not spawn along with the structure. To spawn the Lost Explorer, interact with the Suitcase when holding an Emerald.

Other Blocks

• Packed Ice Bricks can be crafted using Packed Ice. There is also Chiseled Packed Ice with a snowflake pattern!

Experimental Toggles

• You can find the toggles in World Settings under the Game section.
• These toggles must be turned on:
  • Holiday Creator Features
  • Creation of Custom Biomes
  • Experimental Molang Features
• The Caves & Cliffs toggle is optional. It is recommended to turn it on for better cave generation; but if your device cannot handle it, do not turn it on. The add-on will still function as normal.
• Backup your world first if you are turning on these toggles on an existing world!

Known Issues

• The thick green fog from the Slimy Sewers, the yellow fog from the Limestone Caves and the blue fog from the Ice Caves also appear on the surface.
• Efficiency can be applied to Luminite tools but there will be no effect. This is a Minecraft bug.
• Due to technical limitations, Radiant Vines, Dripping Slime, Sandy Roots and Dripping Icicles will not break when a supporting block is broken.
• Due to technical limitations, Luminous Mushrooms, Radiant Vines, Slime Layers, Slimy Blossoms, Slimy Sprouts, Dripping Slime, Sandy Roots, Sand Layers, Dripping Icicles, Ice Crystals and Suitcases do not get destroyed by water or lava and are not able to be waterlogged.
• Some errors may show up when generating a world. These errors do not affect gameplay in any way and can be safely ignored. To turn off the error log, go to Settings > Creator > turn off “Enable Content Log GUI”.
• World generation may take a bit longer when this add-on is activated. If the progress bar gets stuck, force close Minecraft and try again. If this repeatedly occurs, open your world without the Caves & Cliffs toggle.
• There is a known bug in Minecraft 1.17.30 that causes chunk errors in your world. This add-on does not have anything to do with this bug. It is very important to backup your world!

This add-on may decrease performance on lower-end and weaker devices.

Please report any bugs you find! Suggestions are also welcome.
