Defiled Lands

Defiled biomes generate in the world with their own creatures and plants, and the terrain inside them converts blocks placed there into defiled blocks that hold unique resources. The defiled ground normally spreads about 3 blocks past its natural boundary and stops there, though the config can change that limit, and a defiled block placed outside the natural area spreads from that point. Defiled blocks can also be used as decoration, so builders can use the look without the biome around them.

The biomes feed a progression route: the materials they yield are used to craft unique tools and gear, and they lead to a boss fight that the mod adds. Detailed information on the biomes, spread rules and crafting is kept on the project wiki. The mod works alongside many other biome-adding mods, including Biomes O' Plenty, and it also uses modified assets from the Painterly Pack by permission of its author, Rhodox.
