About this project
What does Ion: Biomes & Blocks add?
About
The mod adds various features to different areas of the game, such as biomes, ores, new blocks variants and mechanics.
Features
The mod features new unique mechanics and blocks, such as a new type of sand - white, a rich selection of crystals of various colors, and new mechanics for making bricks. And this is even a small part of the mod - it also adds 8 unique biomes, a new ore in the End, different types of windows (including slabs of them)
Biomes
There are 8 biomes in this mod. There are also 3 biomes for generating cave crystals, but they don't count. Of these, I will cite some of the most interesting:
Honey caves
Honey caves are a biome in which Honey Trees and new plants grow - Honey Flower. The biome is illuminated by Honey Crystals - blocks of orange crystals. Bees are also sometimes generated in the biome, due to hives in the trees.
Glowshroom caves
Glowshroom caves are caves with huge glowshrooms, spore lamps, and bushes of violet glowberries. Purple cave crystals are also generated here.
Fall Forest
The fall forest is a forest where birch trees and oaks with orange leaves grow. Foxes also live here, and birch mushrooms grow.
