Guide talk:Farming Biome Keys or Key Molds

IOS: A question, do you need blocks to make biomes (e.g. Ice blocks for snow biome, ebonstone blocks for corruption biome) in the ocean for it to drop key molds? I've been farming in the ocean for ages, I'm just checking if im doing it right. -- 203.104.11.24 23:50, 12 February 2015 (UTC)?
