Black Ice Glaciers

Black Ice Glaciers is a nether biome added by Jaden's Nether Expansion. It is a sub-biome of Soul Sand Valley, so the Nether's biome mosaic places it among the valley terrain. It is a cold patch of the Nether with black ice on the ground, sheets of thin black ice over open air, and ice formations rising from the floor and hanging from the ceiling. Players cross it for the Black Ice it produces and for the freezing hazard the ice poses, and it holds several hostile mobs, including apparitions and vessels.

Description

Black Ice Glaciers has a sky colour of #6eb1ff, a fog colour of #191c22 and a water colour of #3f76e4. The fog is dark, while the sky is bright blue, so the biome reads as a frozen cavern beneath an open sky. The biome has no precipitation.

The floor is mostly soul sand and soul permafrost, and the ceiling is covered in soul sand and soul permafrost. Pale soul slate, a variant of Soul Slate, forms many of the floor patches. Black ice spreads across the floor in wide sheets, and thin black ice fills open air close to the ground. Ice formations rise from the floor and hang from the ceiling. The biome has its own ambient soundtrack and a glacier particle that drifts through the air at a 1.91% chance per tick.

Black ice

Black Ice is the main block of the biome. There are three forms:

• Black Ice is the solid block. It appears in streaks, disks and surface patches.
• Thin Black Ice forms the thin sheets. A player who walks on it breaks it with a 1.5% chance per step. Sprinting raises that chance to 20%, and standing close to the ice raises it to 40%.
• Grooved Black Ice is a grooved variant of the solid block.

Black ice is a hazard. Creatures that stay on black ice freeze after 400 ticks (20 seconds). Thin black ice that touches water freezes it with a 60% chance.

Ectoplasm

Ectoplasm lakes lie in the biome. Ectoplasm is a fluid that freezes ticks and rusts netherite, and both effects are on by default. Ectoplasm can also be stored in a cauldron.

Generation

Black Ice Glaciers has a temperature of 2 and a downfall of 0. It generates only in the Nether. It is tagged as a Nether biome and as a Soul Sand Valley sub-biome, so it is placed by the Nether's biome mosaic.

The biome has 87 structures available to it. The list includes Nether bastions and fortresses from several mods, such as Bastion Remnant and Fortress, along with pack structures such as Mega Fossils and Chapel and Sanctum.

The Nether's surface rules apply to the biome. On ceilings, the surface is soul sand with soul permafrost on top. On floors, soul permafrost forms patches between Y 30 and Y 35, and soul sand covers the rest.

The biome's spawn tables are:

• Hostile creatures: Ghast (weight 50), Apparition (weight 30), Vessel (weight 30), Stray (weight 20), Ecto Slab (weight 10), Stampede (weight 5), Enderman (weight 1) and Mutant Enderman (weight 1).
• Passive creatures: Strider (weight 60).
• Water creatures: a set of water creatures from Nether mods, with weights from 2 to 10.

Strays in the biome spawn under monster spawn rules, so they can appear at any light level. Born in Chaos spawn modifiers are limited to the Overworld in this pack, so no Born in Chaos creatures spawn in the biome.

Features

The biome has a set of features unique to it. Counts are per chunk.

• Black ice clusters are dripstone-style columns of black ice. Ten to fifteen clusters generate per chunk. Each is 6 to 9 blocks tall, with a radius of 2 to 8 blocks.
• Black ice streaks are disks of black ice that replace netherrack and pale soul slate. Forty-five generate per chunk, each with a radius of 5 to 6 blocks.
• Black ice surfaces are disks of black ice that replace soul permafrost. Twenty-six generate per chunk, each with a radius of 5 to 6 blocks.
• Thin black ice sheets are flat disks of thin black ice placed in open air. Twenty-seven generate per chunk, each with a radius of 7 to 8 blocks.
• Freeze lava turns lava at Y 32 into thin black ice. Twelve to fifteen disks generate per chunk, each with a radius of 8 blocks.
• Ice ribs are stamped ice structures in small, medium, big and large sizes, placed on black ice.
• Pale soul slate covers the floor with 128 patches per chunk.
• Ectoplasm lakes are placed in the biome.

Nether features from the mosaic, such as soul swirls, bone pikes, fossil ore, netherrack speleothems, soul magma and pyroclast crusts, also appear in the biome.

Mobs and structures

The biome's hostile mobs include the Apparition, the Vessel, the Ecto Slab and the Stampede. Apparitions can possess mobs and gargoyle statues. Vessels fire volleys of bullets. Ecto slabs burrow and emerge from the ground. Stampedes are large mounts that can be tamed by feeding them roasted bones.

Tips

• Watch the ground when crossing the biome's black ice sheets. Thin black ice breaks under the feet, and falling through a broken sheet is the main risk.
• Do not stand on black ice for long. A creature that stays on it freezes after 400 ticks.
• Expect strays on the valley floor at any time. They use monster spawn rules here, so they are not limited to darkness.
• The Antidotes potion and its immunity effects are useful against the status effects that the biome's mobs apply.
