Soul of Night is a Hardmode crafting material dropped by all enemies killed in the Underground Corruption or Underground Crimson, with a 20% chance. This includes stray enemies not native to the biome, such as Goblins or even monsters of "evil" biomes like The Underworld. Crafting all items, excluding the Boss-summoning items, requires 87 Souls of Night. One of each Boss-summoning item requires an additional 12 Souls of Night, for a total of 99.

- Drop rate increased from 1 in 7 (~14%) to 1 in 5 (20%).
- Stack limit increased from 250 to 999.
