The Underground Hallow is a Hardmode Biome, being one of the biomes that spawns when the Wall of Flesh is defeated. It is the underground version of the surface-level Hallow, and appears at and below the cavern layer. It operates similarly to surface Hallow, being comprised of Pearlstone and Pearlsand; though it spawns different enemies, along with Crystal Shards, a common Hardmode crafting material. Underground Hallow spreads just like surface Hallow, and similarly can not spread to Corruption (nor to Underground Corruption).
All enemies killed in the Underground Hallow have a chance to drop a Soul of Light.
Note: Most characteristics of surface Hallow apply to the Underground Hallow, with the exception of the enemies that spawn. See The Hallow for more extensive information.
