New biome
This biome will rarely appear, but you can find it near the Snowy Tundra biome. If you can’t find this biome yourself, then enter the world with seed 100 and move to coordinates (-2600, 64, -2400).
After you find the Frozen Plains biome, start exploring it and you will find the entrances to new caves pretty quickly. They come in a variety of sizes, from small to just gigantic.
In these caves, in addition to the large amount of ice, ice stalagmites can form, which look just incredible.
Also in these caves there is a new resource, namely frozen iron, which is mined a little longer and can immediately generate up to 8 blocks.
To get a regular block of iron ore from frozen iron, you will need to put it in a furnace and melt it.
