this mod is quite an interesting one. It makes Mobs like the creeper and the wither skeleton much easier to farm by making them spawn in a biome where only said mobs spawn.
charred Forest This new biome isn't the safest, indeed so, Only Wither and regular skeletons spawn at night and can take you down quickly without armor. on the bright side, build a normal mob farm, and you have an infinite supply of wither skulls, arrows, bones and coal. There's also a new black wood type: Charred wood, which is amazing for building.
Whitebark grove This green and red forest makes creepers and animals spawn. much like the Charred forest, it is home to a new wood type, Whitebark pine, it is White and is also great for building! build a normal mob farm for an infinite supply of gunpowder!
