Souls

Souls are Hardmode crafting materials dropped by enemies. There are a total of 6 /  7 types of souls. The most common ones are the Souls of Light and Night, which are dropped in the Underground Hallow and Underground Corruption/Crimson, respectively. Most of the remaining souls drop from the mechanical bosses.

Tips

 * An easy way to obtain Souls of Night and Light is to go to the Dungeon and spray Red/Purple/Blue Solution with the Clentaminator at different areas, converting the area into the respective biome. Because of the Dungeon's high spawn rate, it is possible to get a large amount of souls fairly quickly.
 * Another very effective way to farm Souls of Night and Light is to craft a Slime Crown and summon King Slime in the appropriate underground biome. Each fight often yields over 20 souls from all of the slimes that are spawned.

Trivia

 * All of the souls' names rhyme with each other ().
 * Souls of Blight are the only souls without an animation. This is because they are unavailable on 1.3, the update which introduced animated soul sprites.
 * There is only one soul whose tooltip directly states the name of the enemy it is dropped from, the Soul of Might.
 * It is also the only soul that is obtainable pre-Hardmode.
