Biomes O' Plenty

Biomes o' Plenty is a worldgen mod that adds 60 new biomes, new gems and a whole new dimension. The mod is not only focused on realistic biomes; there's fantasy biomes like Fungi Forest and Garden.

Biomes
The main scoop of the mod is of course the biomes. Here's a list of them.

Hot Springs
Hot Springs is a snowy biome with small lava lakes and small lakes of 'spring water'. Big spruce trees are scattered around on grassy parts between the stone parts and the lakes.

Hot Springs is a great biome; if you stand in spring water you get a regeneration buff and a nourishment buff, that fully restore both bars over time.
