Talk:Soul of Light/@comment-68.5.50.199-20111204101111

Any mob - absolutely any mob - can drop a soul of light, or soul of night. They simply need to be 1) Underground (appears to require at least the second layer, with the stone background, not the dirt/rock background), and 2) in their respective biome. I have lured corrupters into Hallowed biomes and killed them and received souls of light.
