Hot springs!

Wouldn’t it just be wonderful instead of the measly sulfur pools on the surface that alert of a sulfur cave an entirely new biome spawned known as the hot springs? Steam and water would flow through cracks in a blue-lake bordered in reds and yellows, geysers would blast mist into the air. Sulfer could be used to improve farm land by 5%-20%, and could be used to brew nausea potions, cinnabar would make blindness and red dye. Nausea would reduce pathfinding slightly and reduce arrow accuracy in skeletons. Hot springs could spawn in the warmest biomes and the coldest biomes. Imagine you are traveling with your llama caravan through an Ice Spikes during a blizzard shot at by strays and beaten. That is until you con across and acidic, toasting lake on who’s shores you can make camp to the hissing and sighing of steam and geysers bubbling up. Vote to make it happen!
