Soul of Night

The Soul of Night is a crafting material that is dropped by mobs in the levels under The Corruption by enemies such as the Green Jellyfish, Eater of Souls, Corruptor and Skeleton Archer and all others. Soul of Night can also be obtained from Hallow enemies including Chaos Elemental and Illuminant Bat if killed inside Underground Corruption. Drop chance appears to increase when near the nodes of ebonstone with the dark lights or by extremely rare Alters made by Red Torches and Stone.
