Cold nether

The mod adds a new dimension modeled on the Nether but covered in ice. Its biomes, called cold valleys, warm valleys and the frozen overworld caves, hold icy stone and icy granite, lapis and frozen ores, and the rarest ore, coal, appears only in the lava lakes. Icy stone drops ordinary stone when mined. Liquid nitrogen fills many low areas and damages the player by two hearts per second, so a trip into the dimension calls for preparation. Darkness there also means that torches or a night vision potion help players see.

Frozen piglins appear only in this dimension and drop blue berries, which are the only food source there. The berries have four growth stages in the current version, grow faster with bonemeal on frozen grass, and are picked up with an ice knife. A new type of tree, the dwarf pine, drops a frozen pine sapling when smelted and grows frozen leaves. Villagers trade items made with packed ice, and structures such as small frozen houses, small pine houses, abandoned houses and wells generate in the dimension, along with an ice shard block.
